ABSTRACT:
In a combination of a metal chain and a J-shaped hook, a first ring of the metal chain is connected to a J-shaped hook through a hole provided in a bottom thereof. Therefore, the J-shaped hook can rotate about the first ring at the connection hole and be changed into an approximately inverted J-character shape when hanging from the metal chain in case the chain hook is not used. Moreover, the head portion of the J-shaped hook can be in contact with and held by the first ring so as to keep an approximately J-character shape along the metal chain when the chain hook is used.
