Plug-in connection with leakage protection
First Claim
1. A plug-in connection for connection with a plug-in part comprising a receiving housing with a plug-in opening for the plug-in part, a circumferential seal for sealing a circular gap between the receiving housing and the inserted plug-in part, a valve element, which, when the connection is disconnected, automatically closes the receiving housing in order to provide run-out protection, and the valve element, when the plug-in part is inserted into the housing, is opened by the plug-in part, the valve element closing the receiving housing by engaging the same circumferential seal as does the plug-in part in its inserted position whereby the valve element is part of a pre-assembled valve cartridge which comprises an inner insert housing, the valve element, located inside the insert housing, and a spring element, which generates a spring force acting on the valve element in the direction of closure.

Abstract
A plug-in connection for connecting a plug-in part especially one formed by one end of a pipe line consisting of a receiving housing with a plug-in opening for the plug-in part, a circumferential seal for sealing a circular gap between the receiving housing and the inserted plug-in part as well as a valve element, which, when it is disconnected, automatically closes the receiving housing 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. The valve element in order to close the receiving housing directly engages the same circumferential seal, which seals the plug-in part.
