Claim:
A spigot-and-socket joint for connecting two pipes, pipe fittings or the like, having a longitudinal axis, comprising a socket end which is assigned to one pipe and into which a spigot end of the other pipe, which has a support strip, can be inserted, the socket end having a radially inward-protruding edge with at least one ring segment-shaped recess, and a locking device for locking the spigot end in the socket end, in that the support strip rests against the locking device and said locking device rests against the edge, the locking device comprising at least two ring segment-shaped locking elements, wherein at least four recesses are provided in the edge and are arranged with uniform spacing in the circumferential direction, wherein the two locking elements each have two ring segment-shaped locking parts which are joined together via a respective web, the spacing between the two locking parts of each locking element corresponding to the spacing between two of the recesses, and further wherein the retaining element lies parallel to the web between the two locking parts and rests against the edge and thus prevents rotation of the locking element in the socket end.
