The device (1) has a displacement part (2) e.g. clamping device (4), movable to a displacement direction of a displaceable element along guides with a cam. The guides are mountable on the element or on a stationary part. The displacement part is pullable via a spring unit from a moved-out position into a moved-in position. The cam co-operates with curved pathways provided on a curved element that is attachable to the stationary part or to the element. A clamping holding of the displacement part is releasable when the cam of the displacement part reaches a maximum of curved pathways (6, 7). |
