Abstract

A push-fit pipe coupling comprises a moulded plastics body 1 defining a socket 3 to receive a pipe-retaining member 23 and/or a seal 21, the coupling body having a relaxed condition in which the socket has a internal diameter which is substantially constant or increases from its inner to its outer end, and longitudinal slots 73 such that the socket region of the body can be radially collapsed. The coupling body is moulded in its relaxed configuration with a simple core, since it does not contain inner regions of internal diameter greater than axially outer regions. While the socket is in its relaxed or expanded condition, a seal ring and/or a pipe-retaining component can be inserted into it very easily. The socket is then collapsed to a condition in which its axially outer region is of reduced diameter, thereby retaining the seal ring and/or pipe-retaining component. The coupling socket is then fixed in this collapsed condition, preferably by the application of a external metal reinforcing and retaining sleeve or cap 25. In a preferred arrangement the internal surface of the socket and the external surface of a pipe-retaining component interact as wedges, forcing the pipe retaining component into tight radial engagement with the outer surface of an inserted pipe end. <IMAGE>
