PROBLEM TO BE SOLVED: To provide metal fittings which easily connect to constant position in the case of connection by utilizing the properties of magnets of the same size that the magnets connects to the same position and are strong to vertical adhesion but are weak to horizontal deviation, to easily disconnect the accessory by utilizing the properties that the magnets are weak to the deviation, and to reinforce a weakness to pulling forces in directions A and B by utilizing a projection (pawl). SOLUTION: A plate-like or rod-like projection (pawl) is added to box-like or tube-like metal fittings covering the magnet of an arbitrary shape except for the a joint face of the metal fittings, and a round tube for mounting a necklace is attached on the opposite face of the projection (pawl). Further, when fixing the magnet inside of a metal fitting body, a gap is kept with the projection (pawl). Two metal fittings of the same shape are overlapped, for use, so that the projection (pawl) is positioned in an upper or lower portion of the confronted round tube when overlapping.
