Abstract

A plug-in part in the form of a piece of tubing and having a sealing portion, the sealing portion comprising a sealing element enclosing the piece of tubing in a circumferential direction, and a locking portion with at least one undercut. The plug-in part is adapted to be plugged into the receptacle of a coupling part of the plug connector arrangement in order to produce a fluid-tight connection. At least one locking element of the coupling part engages behind the plug-in part in the region of the undercut. In order to develop the plug-in part so as to reduce the risk of the sealing element being adversely affected, the undercut is formed by a protrusion which projects from the outside of the piece of tubing and extends circumferentially merely over a sub-region of the piece of tubing.
