Abstract
A plug-in coupling for pipes includes a sealing element, a sleeve linked with the base and a retaining element including retaining claws for fixing the pipe end which is disposed in the interior of the sleeve. An annular gap between the base and the sleeve and receives the pipe end. While reducing production and assembly costs, the plug-in coupling ensures a durable and reliable connection and prevents the pipe end from being damaged and the retaining claws from penetrating the pipe end too deeply. The retaining element includes a closed annular part and is integrated into the sleeve and fixed therein with said part. The sleeve includes radially inside the retaining element a support element with an outer supporting face on which the spring-elastic retaining elements are supported. The supporting face is mounted at a predetermined angle which opens up towards the free front sleeve end.
