PURPOSE: To provide the structure of a hanging tool with a connecting function in which a locking metal fitting can be easily attached to and detached from a hanging metal fitting, and also can not be separated from the hanging metal fitting.

CONSTITUTION: In a locking metal fitting 1, a spring 5 and a pressing metal fitting 6 are put around to a pin 4, a locking pin 7 is attached to the tip of the pin 4, oblong holes are bored in one of the ends of the hanging metal fitting 2 and a connecting metal fitting 3 so that the locking pin 7 can be passed therethrough except for a passing hole for the pin 4, and a groove to which the locking pin 7 is inserted is formed outside of the end. The locking metal fitting 1 is passed through the connecting metal fitting 3 and the hanging metal fitting 2, the pin 4 is turned while being pushed when the locking pin 7 comes outside, and the locking pin 7 is inserted to the groove so that spring force is exerted, and the locking metal fitting 1 is locked. A hole through which the locking pin 7 is passed, is not bored at the other end of the hanging metal fitting 2, so that the locking metal fitting 1 may not be separated from the hanging metal fitting 2.
