Abstract

A coupling arrangement connects two elements with each other. The coupling arrangement includes a plug element and a bushing element which are configured in such a manner that they can be plugged together and locked in position by means of an expandable retaining ring. An axially movable release arrangement cooperates with the retaining ring in order to release the locking mechanism. The coupling arrangement is characterized in that the release arrangement (41) comprises a release sleeve (43), which can be closed with a cover (51) on its side facing away from the bushing element (5), and that a blocking device (55) is used to prevent an inadvertent release of the coupling.
