The hook (9) has an open frame (46) comprising an access opening (23) and a closure element (22), which partially closes the opening in one position i.e. idle state, of the element. The closure element is pivotable from the idle state into two opening positions, and is resiliently held in the idle state. The closure element has a distance to a free end (37) of the hook in the idle state, where the free end limits the access opening. The element has side pieces (27, 28) running on opposite sides of the frame. |
