The hook 10 is provided with a coming-off preventing mechanism to prohibit or permit attachment/detachment of the wire 40 by opening/closing the opening P. The wire coming-off preventing mechanism consists of a tubular guide member 20 fixed to one side of the opening P and a rod-shaped member 30 which is passed in the tubular guide member 20 slides in the guide member, and opens the opening P when being moved to one end part and closes the opening P when being moved to the other end part.
