Abstract: The invention relates to a connector for joining pipes, particularly of metal, which comprises a socket and a pipe having a smooth end for insertion into the socket. A seal and friction ring inside the socket seals the pipe into the socket and prevents accidental withdrawal. In the present invention retaining elements are embedded in the elastomeric sealing material of which the ring is composed and are axially slidably guided as well as being freely tiltable about an annular bead on the socket.

Abstract: The invention relates to a socket connection of tubes or tubular elements, in particular of metal, with a plug-in (male) end and a socket (female) end which accommodates the former with radial clearance and has a radially extending inside shoulder against which supports itself in axial direction a one-piece sealing and anti-thrust ring with a foot section and several retaining elements spaced in circumferential direction and engaging with an inside edge of the periphery of the plug-in end whose head portion, located inside axially, seals the annual space between the socket end and the plug-in end.
