According to a third aspect of the present invention, in addition to the effects of the first aspect, the belt adjusting portion provided on the male body loosely fits the hooking rod into the guide groove provided on the side frame of the male body, and The folding rod is placed on the side frame in such a way as to be opposed to the hooking rod, so that even if it is a movable type adjustment unit that can move the hooking rod, the pressing piece presses the belt accurately and pinches it. There is an effect that even a known movable type adjustment unit can be easily applied.

According to a fourth aspect of the present invention, in addition to the effect of the first aspect, the supporting rod disposed on the female housing has elasticity and is formed so as to be resilient in the horizontal direction. There is an effect that the supporting rod elastically presses the belt hooked on the hooking rod, and an appropriate holding state can be realized.

According to a fifth aspect of the present invention, in addition to the effects of the first aspect, the supporting rod disposed on the female housing is bent in a U-shape with its central portion outwardly bent. Is provided, and the pressing piece is formed integrally with the bending portion, whereby there is an effect that elasticity can be imparted to the support rod in a simple form.

According to a sixth aspect of the present invention, in addition to the effect of the first aspect of the present invention, the hooking bar disposed on the side frame of the male body is provided with a locking claw having a wedge-shaped cross section on the insertion side. By forming the belt in such a manner that the belt is pressed against the locking claw by the pressing piece provided on the female support rod, the belt can be pinched accurately and easily, and the belt can be easily prevented from being loosened.

According to a seventh aspect of the present invention, in addition to the effect of the first aspect of the present invention, the pressing piece formed on the female supporting rod is formed on an inclined surface having a shape in which the upper end of the tip protrudes and the lower portion recedes. By doing so, the effects achieved by the present invention are extremely remarkable, such as an effect that the pressing piece can cope with the hooking rod in an appropriate form and that the pressing piece can easily prevent the belt from being loosened.
