The present invention relates to a clamping device for clamping tools, having a receptacle ( 2 ) that is surrounded by an annular space ( 3 ). The annular space ( 3 ) is open toward the workpiece-side end surface ( 1 a) of the chuck body ( 1 ) and toward the receptacle ( 2 ), and is closed off by an cover ( 5 ). 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 ).
