An accessory part to be connected to an operating table has a connecting element (12, 16) and a component part of the operating table has a receiving area (14) for receiving at least an area of the connecting element (12, 16). An engagement element (22, 24) projects laterally from the connecting ele
An accessory part to be connected to an operating table has a connecting element (12, 16) and a component part of the operating table has a receiving area (14) for receiving at least an area of the connecting element (12, 16). An engagement element (22, 24) projects laterally from the connecting element (12, 16). The receiving area (14) has at least one guideway (18, 20) with which the engagement element (22, 24) engages during insertion of at least an area of the connecting element (12, 16) into the receiving area (14). When deformed, an elastically deformable element (52) exerts a force on the engagement element (22, 24). By the force exerted on the engagement element (22, 24) and by the course of the guideway (18, 20) a force (FA) is exerted in the direction of insertion (P2) on the connecting element (12, 16) when the accessory part and the operating table are connected.

1. An arrangement for connecting an accessory part to an operating table, the arrangement comprising: a connecting element adapted to be connected to the accessory part, the connecting element having a substantially cylindrical portion with a hollow interior, at least one opening into the hollow interior being formed in a circumferential surface of the cylindrical portion;an engagement element having an inner cylinder rotationally disposed within the hollow interior of the connecting element and having at least one cylindrical pin that projects radially outward from the inner cylinder and through the at least one opening of the connecting element;an elastically deformable element disposed within the hollow interior of the connecting element, the elastically deformable element resisting rotation of the engagement element within the hollow interior of the connecting element;a component part having a receiving are for receiving at least and area of the substantially cylindrical portion of the connecting element, the component part adapted to be connected to the operating table;wherein the receiving are has a guideway with which the at least one cylindrical pin of the engagement element engages during insertion of the at least an area of the substantially cylindrical portion of the connecting element into the receiving area, wherein the guideway has a rising area and a falling area;wherein upon insertion of the connecting element into the receiving area the engagement element is rotated within the hollow interior against the force of the elastically deformable element by engagement of the at least one cylindrical pin with the rising area of the guideway, andwherein the elastically deformable element, when deformed, exerts a force on the engagement element, wherein by means of the force exerted on the engagement element and by the course of the guideway, when the at least one cylindrical pin of the engagement element engages the falling area of the guideway, a force FA acts in the direction of insertion (P2) on the connecting element when the accessory part and the operating table are connected. 2. The arrangement according to claim 1, wherein the connecting element is formed as a pin and wherein the receiving area is formed as a bushing into which the pin can be inserted. 3. The arrangement according to claim 2, wherein an end of the pin to be inserted into the bushing is tapered. 4. The arrangement according to claim 2, wherein an end of the pin to be inserted into the bushing has a circumferential chamfer. 5. The arrangement according to claim 1, wherein the force acting in the direction of insertion presses a first contact area of the connecting element against a second contact area of the receiving area. 6. The arrangement according to claim 5, wherein the first contact area or the second contact area are formed by at least a part of a circumferential surface of a conical frustum, the longitudinal axis of which runs parallel to the direction of insertion (P2), and wherein, in a connected state of the accessory part and the operating table, the respective other contact area is formed, at least in a partial area, complementarily to the circumferential surface of the conical frustum. 7. The arrangement according to claim 1, wherein by way of the rising area of the guideway, upon insertion of the connecting element into the receiving area, a rotation of the engagement element about an axis of rotation running parallel to the direction of insertion (P2) in a first direction of rotation (P1) takes place, wherein the elastically deformable element is deformed upon rotation of the engagement element in the first direction (P1), and wherein, by the way of the falling area of the guideway, the engagement element is rotated in a second direction of rotation opposite to the first direction of rotation (P1) after passing the first rising area, wherein the elastically deformable element, upon deformation, exerts a force on the receiving area via the engagement element and the guideway, wherein this force is split up into an axial force (FA) in the direction of insertion (P2) and into a radial force (FR) in the second direction of rotation by the second falling area of the guideway, wherein by the force (FA) acting in the direction of insertion (P2) the connecting element is held in the receiving area and/or pulled into the receiving area. 8. The arrangement according to claim 1, wherein a lever is provided which is connected to the engagement element in a rotationally fixed manner, wherein for releasing the connection between the connecting element and the receiving area the engagement element can be rotated with the aid of the lever in the first direction of rotation (P1) so that upon actuation of the lever the connecting element can be moved out of the receiving area opposite to the direction of insertion (P2).
