The fingers 13 are guided along the inner faces of fingers 4 between webs 7 fast with the fingers 4 which at their free ends are provided with recesses 6 co-operating with corresponding projections at the free ends of the fingers 12 which are provided with ribs 14 serving as guides which are received in gaps 5 of fingers 3. The end projections 14a of the ribs 14 define a stop which limits the open position of the fingers. The locked position of the fingers is ensured by ribs 8 provided on the end ones of fingers 4, the ribs being abutted by the free ends of fingers 13.
