A paper clip as claimed in claim 1, wherein: the interior surfaces of the legs are coated with an abrasive material.

Claim 9

A paper clip as claimed in claim 1, wherein: the interior surfaces of the legs are roughened so as to be non-slipping.

Claim 10

A paper clip for clampingly engaging at least two sheets of paper, said paper clip comprising: a body member, substantially U-shaped in longitudinal cross-section, of semi-rigid, generally flexible plastic sheet material, said body member having a pair of legs presenting two substantially planar interior surfaces between which at least two sheets of paper may be clamped, one of said legs being longer than the other and terminating in a free edge having a central longitudinal notch defined therein which extends inwardly from the free edge; and a longitudinally extending substantially rigid, but slightly flexible rigidifying metal member, of substantially smaller transverse cross-section than that of the body member, fixedly secured to said legs away from the interior surfaces thereof so as to present only the planar interior surfaces of the body member to paper sheets clamped therebetween, said metal member is not coextensive with the notch whereby the portion of the longer leg coextensive with the notch is more flexible than any portion secured to the metal member.

Claim 11

A paper clip for clampingly engaging at least two sheets of paper, said paper clip comprising: a body member, substantially U-shaped in longitudinal cross-section, of semi-rigid, generally flexible plastic sheet material, said body member having a pair of legs presenting two substantially planar interior surfaces between which at least two sheets of paper may be clamped, one of said legs being longer than the other and terminating in a free edge having a central longitudinal notch defined therein which extends inwardly from the free edge; and a longitudinally extending substantially rigid, but slightly flexible rigidifying metal member, of substantially smaller transverse cross-section than that of the body member, fixedly secured to said legs away from the interior surfaces thereof so as to present only the planar interior surfaces of the body member to paper sheets clamped therebetween, said metal member is not coextensive with the notch whereby the portion of the longer leg coextensive with the notch is more flexible than any portion secured to the metal member.

Claim 12

A pater clip as claimed in claim 9 wherein: said free edge is substantially arcuate.

Claim 13

A paper clip for clampingly engaging at least two sheets of paper, said paper clip comprising: a body member, substantially U-shaped in longitudinal cross-section, of semi-rigid, generally flexible plastic sheet material, said body member having a pair of legs presenting two substantially planar interior surfaces between which at least two sheets of paper may be clamped, one of said legs being longer than the other and having a hole defined therethrough, adjacent the end thereof most remote from the bight of the U, through which a finger can be inserted to move the legs away from each other for insertion of sheets of paper therebetween; and a longitudinally extending substantially rigid, but slightly flexible rigidifying metal member, of substantially smaller transverse cross-section than that of the body member, fixedly secured to said legs away from the interior surfaces thereof so as to present only the planar interior surfaces of the body member to paper sheets clamped therebetween, said metal member secured to said longer leg being not coextensive with said hole whereby the portion of said longer leg coextensive with said hole is more flexible than any portion secured to the metal member.

Claim 14

A paper clip for clampingly engaging at least two sheets of paper, said paper clip comprising: a body member, substantially U-shaped in longitudinal cross-section, of semi-rigid, generally flexible plastic sheet material, said body member having a pair of legs presenting two substantially planar interior surfaces between which at least two sheets of paper may be clamped, one of said legs being longer than the other and having a hole defined therethrough, adjacent the end thereof most remote from the bight of the U, through which a finger can be inserted to move the legs away from each other for insertion of sheets of paper therebetween; and a longitudinally extending substantially rigid, but slightly flexible rigidifying metal member, of substantially smaller transverse cross-section than that of the body member, fixedly secured to said legs away from the interior surfaces thereof so as to present only the planar interior surfaces of the body member to paper sheets clamped therebetween, said metal member secured to said longer leg being not coextensive with said hole whereby the portion of said longer leg coextensive with said hole is more flexible than any portion secured to the metal member.

Claim 15

A paper clip for clampingly engaging at least two sheets of paper, said clip comprising: a body member, substantially U-shaped in longitudinal cross-section, of semi-rigid, generally flexible plastic sheet material, said body member having a pair of legs presenting two substantially planar interior surfaces between which at least two sheets of paper may be clamped; one of said legs comprises a pair of first longitudinally extending leg members transversely spaced from each other to define a longitudinally extending slot therebetween which extends inwardly from the free edge of said one leg; the other of said legs comprises a second leg member, substantially coextensive with said slot but of a width slightly less than that of the slot, which may extend through the slot when paper sheets are not clampingly engaged between said first and second legs; a pair of substantially longitudinally extending substantially rigid; but slightly flexible rigidifying metal members, of substantially smaller transverse cross-section than that of said body member, fixedly secured to said body member away from the interior surfaces thereof so as to present only the planar interior surfaces of the body member to paper sheets clamped therebetween; one of said pair of metal members being substantially centrally disposed relative to and fixedly secured to one of said pair of first leg members, said one metal member also being fixedly secured to a portion of the other of said legs other than said second leg member; and the other of said pair of metal members being substantially centrally disposed relative to and fixedly secured to the other of said pair of first leg members, said other metal member also being fixedly secured to portion of the other of said legs other than said second leg member whereby said second leg member is more flexible than any part of the body member secured to said metal members.

Claim 16

A paper clip for clampingly engaging at least two sheets of paper, said clip comprising: a body member, substantially U-shaped in longitudinal cross-section, of semi-rigid, generally flexible plastic sheet material, said body member having a pair of legs presenting two substantially planar interior surfaces between which at least two sheets of paper may be clamped; one of said legs comprises a pair of first longitudinally extending leg members transversely spaced from each other to define a longitudinally extending slot therebetween which extends inwardly from the free edge of said one leg; the other of said legs comprises a second leg member, substantially coextensive with said slot but of a width slightly less than that of the slot, which may extend through the slot when paper sheets are not clampingly engaged between said first and second legs; a pair of substantially longitudinally extending substantially rigid; but slightly flexible rigidifying metal members, of substantially smaller transverse cross-section than that of said body member, fixedly secured to said body member away from the interior surfaces thereof so as to present only the planar interior surfaces of the body member to paper sheets clamped therebetween; one of said pair of metal members being substantially centrally disposed relative to and fixedly secured to one of said pair of first leg members, said one metal member also being fixedly secured to a portion of the other of said legs other than said second leg member; and the other of said pair of metal members being substantially centrally disposed relative to and fixedly secured to the other of said pair of first leg members, said other metal member also being fixedly secured to portion of the other of said legs other than said second leg member whereby said second leg member is more flexible than any part of the body member secured to said metal members.
