  • Patent number: 5393107
    Abstract: The spigot-and-socket joint which is secured against sliding is designated to connect the spigot end (3) of a pipe which can be slid into the socket end (2) of another pipe, with radial play existing. In the socket end there are arranged a sealing ring (8) and a separate clamping ring (14) comprising a plurality of circumferentially extending, spaced clamping segments (15) having a spherically convex outer surface (17) and, on an inner surface, a tooth system (19) which, in the presence of axial forces, presses radially onto the spigot end (3) as the spherically convex surface (17) cooperates with a pipe socket's inner surface (18) which tapers conically towards the end. An elastomeric support member (20), which can be fixed in its position at the socket front end and supports the same, is provided on the clamping ring (14).
