The invention relates to a fixing device, comprising two clamping jaws (33) arranged symmetrically to each other and each having a through hole (38) for a rod (12) or shaft passing through same, and an actuating piston (27) which can be actuated by means of a fluid in a piston chamber. The fixing device also comprises an actuating lug (30) which can be moved by the actuating piston for engaging the clamping jaws and moving them away from each other against the force of a spring (36) and about a pivoting bearing (35) from a first into an open second position. The center of each through hole is at a first distance to the pivoting bearing and at a second distance to the area where each actuating lug engages each clamping jaw. The invention is characterized in that the second distance is smaller than the first distance. |
