Description of the Related Art For example, in a conventional shackle, a mounting hole is formed through each of the opposing tips of a substantially U-shaped metal fitting body, and one of the mounting holes has a screw formed on its inner surface. To form screw holes, shackle pins (connecting pins) are inserted into the respective mounting holes, and the screw portions formed at the tips of the connecting pins are screwed into the screw holes, so that the connecting pins are opposed to each other. It is configured to be screwed and installed between them.
