ABSTRACT:
A spigot-and-socket joint for connecting two pipes, comprising a socket end assigned to one pipe and into which a spigot end of the other pipe, which has a support strip, can be inserted and which has 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. The support strip rests against the locking device and the locking device rests against the edge. The locking device comprises at least two ring segment-shaped locking elements. At least four recesses are provided and are arranged with uniform spacing circumferentially, and 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 a locking element corresponds to the spacing between two recesses.
