ABSTRACT:
A plug-in connection (1) for connecting a plug-in part (2)--especially one formed by one end of a pipe line (4)--consisting of a receiving housing (10) with a plug-in opening (12) for the plug-in part (2), a circumferential seal (14) for sealing a circular gap between the receiving housing (10) and the inserted plug-in part (2) as well as a valve element (16), which, when it is disconnected, automatically closes the receiving housing (10) in order to provide run-out protection and which valve element, when it is inserted, is to be opened by means of the plug-in part (2). The valve element (16)--in order to close the receiving housing (10)--directly engages the same circumferential seal (14), which seals the plug-in part (2).
