The present invention relates to a clamping claw (10) for attachment to a slide rail (100) of a surgical table, the slide rail having a rectangular cross section. The clamping claw comprises a main portion 12 having at least one support surface 37,38 designed to be supported on the slide rail 100 and a main portion 12 attached to the main portion 12 and rotatable about a first rotational axis X And a clamping structure (14) having a mounted shaft (20) and at least one support element (19). The clamping claw 10 also has an actuating element 22 which is rotatably secured to the shaft 20 and which can be moved from a starting position to a fixed position by pivoting movement. The clamping structure 14 is in a locked state in which the support surfaces 37,38 of the main portion and the support elements 19 of the clamping structure 14 are seated in the slide rail 100. In this position, Further, the shaft 20 has eccentricities 56 and 72 pivotable about the first rotation axis X. [ The support element 19 is pivotally mounted about a second rotational axis Y fixed about the eccentric 56 and 72 and parallel to the first rotational axis X. [ The pivotal movement of the support element 19 from the initial position 81 to the support position 77 during the pivotal movement of the actuating element 22 further pivots the slide rail 100 to the clamping structure 14, ). <； / RTI >； It is also possible to operate at an intermediate position between the starting position 83 and the locking position 23 when the pivoting movement of the supporting element 19 is blocked at an intermediate position between the initial position 81 and the supporting position 77 of the supporting element A locking arrangement 27 is provided for blocking the pivotal movement of the element 22.본 발명은 수술대의 슬라이드 레일(100)에 부착하기 위한 클램핑 클로(10)에 관한 것이며, 상기 슬라이드 레일은 직사각형 단면을 갖는다. 클램핑 클로는 슬라이드 레일(100)에 지지되도록 설계된 적어도 하나의 지지 표면(37, 38)을 갖는 메인부(12)와 메인부(12)에 부착되고 제1 회전축(X) 중심으로 회전 가능한 방식으로 장착된 샤프트(20) 및 적어도 하나의 지지 요소(
