Can be unfolded and expanded and removed from the arm. However, when the band portion is not a non-extending metal band as described above, but is an extending band such as a leather band, a urethane band, or a metal band with holes, usually,
A buckle-type stopper is used, and the one-touch type double-bend clasp as described above is usually not used.

[0008] However, the buckle type stopper has a problem that the operation of releasing the band is troublesome as compared with the case of using the above-mentioned double-folded clasp. Therefore, a two-folded folding clasp which can be applied to an extension band has been proposed (for example, see Japanese Utility Model Publication No. 3-35130).
As shown in FIG. 8, the two-piece folding clasp (50B) of this proposal is interposed between one half-side leather band 1 and the other half-side leather band 2, and is made of sheet metal such as stainless steel. The outer plate-like piece 11 and the inner side which are connected to each other via a hinge portion 13 so as to be able to be folded inward with respect to the arm and to be deployed outwardly in the same manner as described above.
