ABSTRACT:
A pipe coupling, suitable for manufacture entirely of plastics material, for any diameter of pipe and internal pressure, has a gripping ring housed in a socket with projections extending through apertures in the socket and terminating in camming portions, which cooperate with camming portions inside a sleeve rotatable on the socket to cause the gripping ring to be urged inwards into gripping contact with a pipe inserted into the socket, which also houses a sealing ring for effecting sealing between the inserted pipe and the socket.
