Clamping device, the inner taper ring (3) of which is seated with its cylindrical inner circumferential surface directly or indirectly on a cylindrical outer circumferential surface of a driven shaft portion (1) and the outer taper ring (4) of which is seated on the tapered outer circumferential surface of the inner taper ring (3), with tightening screws (5), coaxial with the shaft portion (1), by means of which the taper rings (3, 4) can be clamped together and the inner taper ring (3) can be clamped to the shaft portion (1), the pair consisting of the cylindrical inner and outer circumferential surfaces being pressurisable with a liquid pressure medium via grooves (6) provided in at least one of these cylindrical surfaces. In order to make such a clamping device easy to assemble and allow it to be unclamped without releasing the tightening screws (5), it is proposed that an output sleeve (2, 3) be seated on the shaft portion (1) and that its axial length be greater by at least the axial length of an output element (2) than the axial length of the taper rings (3, 4) and that the pressurisation of the pair of cylindrical surfaces with pressure medium be used as the hydraulic release mechanism for the clamping between the shaft portion (1) and the output sleeve (2, 3).
