Configured in the receptacle-side inner wall of the cover (5) is an annular groove (13) in which a sealing ring (12) is arranged; a liquid can be delivered to the annular groove (13) in order to press inward the sealing ring (12) that is inserted into the annular groove (13) and thus actively seal a gap formed between the cover (5) and a tool (W) inserted into the receptacle (2).
