To provide a small-sized, clean and easy-to-wear clip with an excellent wearing feeling for a wrist band.

Bosses 18 are inserted into set holes 44 formed on a band part 40, the wrist band 20 is attached to the clip 10, then the wrist band 20 is wound around the wrist and the bosses 18 are inserted into band holes 22. Then, a female clip 14 is bent and closed to the side of a male clip 12 through a hinge 16. By inserting a pair of the bosses 18 simultaneously into two band holes 22, shakiness and play, etc., are prevented. Since the clip 10 is formed of a synthetic resin material such as polyethylene, the clip does not stimulate the skin or the like. And further, antibacterial coating is applied to the surface and the propagation of bacteria stuck to the clip 10 is suppressed.
