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 plug-in part as well as a valve element, which, when the connection is disconnected, the valve element automatically closes the receiving housing to provide run-out protection, and when the plug-in part is inserted into the housing, the valve element is opened by the plug-in part and the valve element closing the receiving housing, by engaging the circumferential seal, whereby the valve element includes a contact section for the purpose of a direct contact with the plug-in part which is constructed such that contact between an outlet opening of the plug-in part and the contact section forms at least one flow passage, the contact section comprising of at least two essentially radial ridges jointly defining an essentially conical outer enveloping surface with a point which is turned toward the plug-in part, and the contact section of the valve element having a maximum diameter, which is larger than the inner diameter of the outlet opening of the plug-in part such that the outlet opening with its opening edge reaches a contact position in the intermediate region of the contact section.

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).
