Abstract
The plug-in socket joint secured against sliding movement is intended for socket pipes (1) manufactured by centrifugal casting, in which the spigot end (3) of one pipe may be inserted with radial play into the socket end (2) of the other pipe. In this joint, a sealing ring (8) and a clamping ring (14) structurally separate therefrom are arranged, said clamping ring being composed of a plurality of clamping segments (15) spaced from one another in peripheral direction. The latter have a spherical outer shell surface (17), are connected to each other in peripheral direction by means of a moulded-on intermediate layer of rubber or similar and each have a toothing (19) on their inner surface (18). A holding part (20), which may be fixed in the area of the socket face end and supporting same, is formed on the clamping ring (14) and comprises a connecting section (24) extending to the clamping ring (14) and tapering approximately conically, and may be expanded together with the clamping ring (14) in dependence on the outer dimensions of the spigot end (3) to be inserted and may thus be extended in axial direction. To prevent the toothing (19) of the clamping segments (15) from corroding …
