Abstract

The invention relates to a plug-in coupling, comprising a base body (6), a sealing ring (12, 13), a locking ring (40) and an annular body which can be connected to the base body (6). A pipe end (4, 5) can be locked in position, using the locking ring (40). The invention aims to improve the plug-in coupling, so that a connection can be made with at least one pipe end in a simple, functionally safe manner, whereby pipes consisting of different materials can be used. According to the invention, the pipe end (4, 5) can be inserted into an axial annular gap (27) between the base body (6) and the annular body (18, 19) in such a way that the sealing ring (12) lies adjacent to the interior of the pipe end (4, 5), making a good seal with the same and that in addition, the locking ring (40) is located in the annular gap (27). Said locking ring is prestressed and adjoins the locking surface (20) of the annular body (18) on one side and the exterior surface of the inserted pipe end (4, 5) on the other side. In addition, a locking ring (40) is situated in the annular gap (27) which is prestressed and adjoins the locking surface (20, 21) of the annular body (18, 19) on one side and the exterior surface of the inserted pipe end (4, 5) on the other.
