Abstract

A pipe coupling comprising a tubular spigot (1) and a sleeve (3). In use, a free end of the spigot (1) is inserted into an open end of tubular pipe and sleeve (3) is pushed over the end of the pipe so that the pipe is gripped between a spigot (1) and the sleeve (3). The outer surface of the spigot (1) defines a plurality of circumferential ribs (4) and grooves. The outside diameter of the ribs (4) increases in a direction away from the free end of the spigot (1). Each groove is dimensioned such that the groove volume is at least as great as the volume of material displaced as a result of the adjacent rib (4) being forced into the pipe wall as a coupling is assembled. The arrangement is such that an end load on the coupling is distributed between the different grooves regardless of whether or not the pipe wall is relatively thick.
