Abstract: A plug-in connector part for a plug-in connection, the plug-in connector part including a housing having first and second housing parts which are screw-connected together by a releasable screw connection. A fixed toothing is fixed on the first housing part and a locking ring and a preload spring are mounted on the second housing part. The locking ring is mounted on the second housing part so as to be displaceable and the preload spring preloads the locking ring in a direction toward an engagement position and the locking ring engages in the fixed toothing in the engagement position. With the locking ring in the engagement position, the screw connection is blocked in the connected state to prevent the screw connection being unscrewed. The locking ring is movable to a release position where the screw connection is rotatable in the connected state for unscrewing.
