The invention is a clamping device for fastening a draw-in bolt to a machine table or a baseplate. The clamping device has a piston axially displaceable in a recess of the machine table and which is also hydraulically actuateable. The clamping device also has a cover, a clamping mechanism, and an integral bushing positioned in the machine table recess. At least one of the piston and the cover form a receptacle into which the draw-in bolt can be inserted through the cover and fastened to the clamping device by the clamping mechanism. The clamping mechanism is actuateable by displacement of the piston. The piston is also displaceable in the bushing with the bushing and the piston cooperating to form a pressure space. The cover is fastened to and centered upon the bushing and is fastenable to the machine table in order to close off the recess.
