Abstract
A locked pipe joint between a socket (3) of a first pipe (4), and a smooth end (1) of a second pipe (2) inserted in the socket with the interposition of an annular sealing gasket (5). The joint includes a raised bead (6) integral with the smooth end, a split metal retaining ring (7), and a rear support surface (9) for the split ring. The split ring includes a series of indentations (19) on the circumference of at least one face (16), in which the indentations are configured to allow the necessary diametric contraction of the ring by the crossing of its ends, and the subsequent expansion of the ring to lock the joint.
