The present invention relates to a shackle comprising: a shackle body having holes respectively formed through two end parts, which are formed due to the opening of one side, having a lifting ring formed due to the closing of the other side, and additionally having an auxiliary lifting ring on the lifting ring; and a shackle pin sequentially passing through and spirally coupled to the holes formed on one side of the shackle body. According to the present invention, apart from the lifting ring, the auxiliary lifting ring is additionally formed on the shackle body, thereby enabling strength reinforcement and preventing two end parts of the lifting ring from transforming inwardly. And since a rope and the like come in contact with multiple points when connected with the lifting ring and the auxiliary lifting ring, wobbling of the shackle is minimized. Also, loosening of the shackle pin is prevented by means of elasticity, bolt or the like. And the end part, through which the front end of the shackle pin is inserted first, of the two end parts of the shackle body is expanded and thus the tensile strength can be increased due to the reinforcement.
