Abstract
A plug-in coupling having a base body ( ), a sealing ring ( ), a locking ring ( ) and an annular body which can be connected to the base body ( ). A pipe end ( ) can be locked in position by the locking ring ( ). The plug-in coupling of the invention enables a connection to be made with at least one pipe end in a simple, functionally reliable manner, in such a way that pipes made of different materials can be used together. The pipe ends ( ) can be inserted into an axial annular gap or space ( ) between the base body ( ) and the annular body ( ) in such a way that the sealing ring ( ) lies adjacent the interior of the pipe end ( ), making a good seal with the pipe end, and also in such a way that the locking ring ( ) is located in the annular gap ( ). The locking ring ( ) is prestressed and adjoins the locking surface ( ) of the annular body ( ) on one side and the exterior surface of the inserted pipe end ( ) on the other side. In addition a locking ring ( ) is situated in the annular gap ( ) which is prestressed and adjoins the locking surface ( ) of the annular body ( ) on one side and the exterior surface of the inserted pipe end ( ) on the other.
