The invention relates to a clamping claw (10) for attaching to a slide rail (100) of an operating table, said slide rail having a rectangular cross-section. The clamping claw comprises a main part (12) with at least one support surface (37, 38) designed to be supported on the slide rail (100) and a clamping structure (14) which is attached to the main part (12) and which has a shaft (20) that is mounted in a rotatable manner about a first rotational axis (X) and at least one support element (19). Furthermore, the clamping claw (10) has an actuation element (22) which is rotationally fixed to the shaft (20) and which can be brought from a starting position (83) into a secured position (23) by means of a pivoting movement. In the secured position, the clamping structure (14) is in a locked state in which the support surface (37, 38) of the main part and the support element (19) of the clamping structure (14) rest on the slide rail (100). Furthermore, the shaft (20) has an eccentric (56, 72) which can be pivoted about the first rotational axis (X). The support element (19) is mounted in a pivotal manner about a second rotational axis (Y) which is stationary relative to the eccentric (56, 72) and which is parallel to the first rotational axis (X). The support element (19) is additionally pivoted onto the slide rail (100) in a pivoting movement from an initial position (81) into a support position (77) during the pivoting movement of the actuation element (22) such that the clamping structure (14) is in the locked state in the support position (77). Furthermore, a locking arrangement (27) is provided which blocks the pivoting movement of the actuation element (22) in an intermediate position between the starting position (83) and the secured position (23) if the pivoting movement of the support element (19) is blocked in an intermediate position between the initial position (81) and the support position (77) of the support element. |
