Where e.g. as in Fig. 4, the inturned lip 6C is inclined and is more liable to expand under high pressure, the blocking ring 12C, here shown as a separate ring, is thicker and has a correspondingly inclined face engaging the lip. A similar blocking ring (12B, Fig. 3, not shown) may be integrally joined to the locking ring by a thin cylindrical section (15) or a blocking ring (12A, Fig. 2, not shown), having oppositely inclined faces one of which engages the lip and the other of which is joined by a narrow neck (14) to the locking ring may be used. The sealing ring, which is e.g. of natural or synthetic rubber, is suitably sectioned to fill the remainder of the recess and is provided with either a ribbed sealing portion 9, Fig. 1, or a rounded flange-like sealing portion 9A, Fig. 4, for sealing engagement between the inserted end of the pipe 11 and the cylindrical portion 3 of the socket when the pipe 11 is fully inserted.
