A connecting structure for swingably connecting two parts such as adjacent pieces and the like of a band includes a plurality of connecting pipes provided on the adjacent parts and aligned along an axis. A connecting pin is inserted into the connecting pipes and carries a C-shaped spring ring which engages with an installation groove of the connecting pin in a manner such that the diameter of the spring ring can be reduced. The connecting pin, together with the spring ring is inserted into the connecting pipes by reducing the diameter thereof, and fastens the connecting pin to the connecting pipes by enlarging the diameter of the spring ring inside the connecting pipes until the outer surface of the spring ring contacts the inner surface of the connecting pipes.
