Abstract
A hook, particularly an eye hook having a forked head. The hook has a hook body which forms a receiving opening for chain links which are to be suspended therein. The hook also has a closure piece detachably fastened to the hook body and projecting into the receiving opening. The closure piece is rigidly arranged on the hook body in such a way that an introduction opening is formed, the inside diameter of which corresponds to the cross sectional dimension of the chain link taken perpendicular to its annular plane.
