Abstract
Abstract A hose coupling comprises a threaded body (12) and hose clamping fingers (18) extending from the body (12), the body (12) and the fingers (18) being formed as a one piece unit in a single manufacturing operation with the fingers (18) being formed with a ridge (28) around the exterior. A-separate slideable collar (34) fits around the fingers (18) and is slideable along the fingers (18) so as to squeeze the fingers (18) together when the collar (34) is pressed towards the body (12), and releases the fingers (18) when the collar (34) is pulled away from the body. The fingers (18) have interior teeth (24) arranged to engage the surface of a hose (H) and bite into it when the fingers are squeezed together by the collar. At the transition between the fingers (18) and the body (34) an interior sealing sleeve (22), of gradually reducing diameter, is provided for making sealing engagement with the outer surface of the hose, when the hose (H) is forced into the sleeve (22).

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
174 words
A hose coupling for attachment to a hose and comprising a body portion 12 defining a bore 14; hose clamping fingers 18 extending from said body portion 12, the body portion 12 and the fingers 18 being formed as a single integral piece unit; ridge means 28 around the exterior of said fingers 18; slidable collar means 34 fitting captively around said fingers 18, and being slidable along said fingers 18 relative to said ridge means 28 so as to squeeze said fingers 18 together when the collar means 34 is slid towards said body portion 12, and releasing said fingers 18 when the collar means 34 is slid away from said body portion 12; interior tooth means 24 on said fingers 18 arranged and located so as to engage the outer surface of said hose, and to bite into it, when said fingers 18 are squeezed together by said collar means 34, and interior sealing sleeve means 22 of gradually reducing diameter for making sealing engagement with the outer surface of said hose.
