Zusammenfassung:	The invention relates to a clamping device (1) for fixing a steady rest (45), said clamping device having a support (10), which has an annular sliding surface (20), and a ring (30) contacting the sliding surface (20) and having a web (35) running in the radial direction, at one end of which web at least one wing (32) is arranged, having a bearing surface complementary to the sliding surface (20). Said clamping device enables a precise fixation of a pin connected to the ring if the clamping device has an abutment (50) which encloses, together with the ring (30), at least one cavity (80) for a fluid on the side of the wing (32) facing away from the sliding surface (20). The cavity (80) can be placed under pressure via a fluid duct (81) that can communicate with the cavity (80), such that the wings (32) are tensioned against the sliding surface (20).
