Abstract
A clevis type hook has one leg formed with a partially closed bore opening and another leg formed with a through bore opening arranged in axial alignment with the partially closed bore opening; the bore openings being sized to loosely rotatably support opposite ends of an oval load pin whose width diameter permits non-rotative slip-fitting within a load chain link. The load pin is removably retained within the bore openings by a retaining device fixed to the other clevis leg.
