Improved unión shackle, essentially characterized in that one of the orifices existing at the ends of the branches emerges from its outer mouth in two equal helical planes of opposite direction, so that the birth of one defines by a step the end of the other, being said steps located diametrically opposite to the hole, which, coinciding with one of the steps described, has a radial notch of sufficient width to allow the passage of a radial tooth emerging from the pin that closes the shackle, whose pin between the limit the existing interior between the head and the tooth is literally smaller than the external spacing of the branches, so that the immobilization of said pin is achieved through the sliding of the tooth on one of the helical planes thanks to the flexible expander effect of the branches of the shackle .
