ABSTRACT:
A clip (8) comprises a bush (20) and a pin (10) adapted to be inserted into the bush, wherein the bush has a leg portion to be expanded in diameter so as to fasten a plurality of members together when the pin is pushed into the bush. The pin includes a flange (11), a shank (12) extending downward from the lower surface of the flange, an engagement pawl (13) connected to the shank, and a coupling pawl (14) disposed below the engagement pawl. The bush includes a ring portion (21) and a leg portion composed of a plurality of legs (23) divided by slits (25) to extend vertically downward from the lower surface of the ring portion. The pin and the bush are connected with one another through a notched thin-walled portion (29) formed between the lower end of the pin and the ring portion of the bush. The pin and the bush are assembled together in a positional relationship where the ring portion of the bush is held between the engagement and coupling pawls of the pin.
