A pipe joint comprises a spigot (20) and a socket (40). The socket (40) is configured such that, when the spigot (20) is inserted in the socket (40), an annular cavity is defined between a radially outer surface of the spigot (20) and a radially inner surface of the socket (40). Alternative wedging mechanisms are disclosed for resisting withdrawal of the spigot (20) from the socket (40) under axial load without causing damage to the spigot (20). |
