ABSTRACT:
A device is provided for preferably adjustably fixing a strap or a two-piece strap for lifting a heavy load, such as the hull of a ship, and hooking it on to the lifting apparatus. It comprises a yoke shaped piece housing a removable case or box, secured thereto by engagement, in corresponding holes in the arms of the yoke and the sides of the case, of parallel shafts, the first two serving in a way known per se for locking the strap by winding same in loops and the third, which is removable, as means for adjusting its length. The arms of the yoke are extended by lugs pierced with holes, either for passing therethrough a removable pin serving for guiding the active strand of the strap towards its hooking point on to the lifting apparatus, or by means of a hook, ring or similar, or by means of a known device, or by engagement of a member for coupling together two pieces disposed head to tail, one receiving a load carrying strap and the other a strap for hooking on to the lifting apparatus.
