The operating unit is configured to move the clamping element into a release position, and includes at least one operating element, in particular an operating lever. The operating element has at least one activation surface for movement of the clamping element into the release position. The activation surface is arranged such that at least one force initiation point of the operating element is movable, upon interaction with a contact surface of an actuating element of the operating unit, as a factor of movement of the operating element on the contact surface.
