Abstract
Abstract A housing with frangible locking elements includes at least one body portion having a cavity for containing an electrical, hydraulic or pneumatic fittig therein. The housing is provided with at least one tongue-like element engageable, in locking fashion, with at least one seating area provided by another housing, a plate or a supporting structure. Once the hook-like end of the tongue is engaged on the seating area, the housing may only be removed from service by destruction of the frangible tongue-like element, indicating visually that unauthorized tampering has taken place. One embodiment of the invention includes housings having living hinges, lockable to form the fitting containing cavity, by utilizing another hook-like shaped tongue element, engageable on a seating area on an opposed marginal edge of the housing. Another embodiment includes the ability to dispose the housing, in selected spaced-apart distance relationship from a mating housing, plate or supporting structure.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
331 words
A frangible housing, said housing defining side walls, said side walls being intermediate one end and another end of said housing, said one and said other end of said housing each carrying openings, said openings residing in a pair of planes extending parallel to one another, at least one tongue-like element, said at least one tongue-like element having one end thereof secured to said housing, the other end of said at least one tongue-like element carrying at least one clamping-like surface thereon, means to non-releasably lockingly clampingly engage said at least one clamping surface to a seating surface carried on another structure, whereby said housing is attachably securable to said other structure when said at least one clamping surface is in touching seating engagement with said seating surface, said at least one tongue having a longitudinal axis, said longitudinal axis extending normal to one of said planes, wherein adjacent portions of said side walls are joined together by a hinge, and wherein other portions of said side walls are separable from one another along a parting line disposed intermediate said one end and said other end of said housing, whereby at least one of said portions of said housing carries one of the said at least one tongue, said longitudinal axis extending parallel to the axis of said parting line, a side acting tongue, said side acting tongue being secured to one of said at least one of said portions of said side walls and extending substantially tangentially to said longitudinal axis, at least one side acting seating surface being configured in another of said at least one of said portions of said side walls, means to clampingly non-releasably lockingly engage a clamping surface of said at least one side acting tongue to said at least one side acting seating surface of said another portion of said side walls, whereby said housing defines a cavity disposed intermediate its side walls and said one end and said another end of said housing.
Claim 2
Dependent Claim
331 words
A frangible housing, said housing defining side walls, said side walls being intermediate one end and another end of said housing, said one and said other end of said housing each carrying openings, said openings residing in a pair of planes extending parallel to one another, at least one tongue-like element, said at least one tongue-like element having one end thereof secured to said housing, the other end of said at least one tongue-like element carrying at least one clamping-like surface thereon, means to non-releasably lockingly clampingly engage said at least one clamping surface to a seating surface carried on another structure, whereby said housing is attachably securable to said other structure when said at least one clamping surface is in touching seating engagement with said seating surface, said at least one tongue having a longitudinal axis, said longitudinal axis extending normal to one of said planes, wherein adjacent portions of said side walls are joined together by a hinge, and wherein other portions of said side walls are separable from one another along a parting line disposed intermediate said one end and said other end of said housing, whereby at least one of said portions of said housing carries one of the said at least one tongue, said longitudinal axis extending parallel to the axis of said parting line, a side acting tongue, said side acting tongue being secured to one of said at least one of said portions of said side walls and extending substantially tangentially to said longitudinal axis, at least one side acting seating surface being configured in another of said at least one of said portions of said side walls, means to clampingly non-releasably lockingly engage a clamping surface of said at least one side acting tongue to said at least one side acting seating surface of said another portion of said side walls, whereby said housing defines a cavity disposed intermediate its side walls and said one end and said another end of said housing.
Claim 3
Dependent Claim
14 words
The apparatus as claimed in claim 1 wherein said housing comprises a unitary construction.
Claim 4
Dependent Claim
25 words
The apparatus as claimed in claim 1 whereby said opening and said another opening disposed in said ends of said housing are of equal size.
Claim 5
Dependent Claim
