PROBLEM TO BE SOLVED: To solve a problem that when a strong external force acts near a proximal end of a nonslip piece of a loop clutch, the piece is easily broken at its proximal end, and to allow a sufficient elastic deformation and improve the molding efficiency of the loop clutch. SOLUTION: A loop clutch 1 has a hook body 11b and a nonslip piece 11c. In the piece 11c, the proximal end thereof is formed integrally with a proximal end part 11c-1 projecting from the base part thereof, and the piece 11c is opened between the part 11c-1 and the hook body 11b so as to project toward the inner surface of the body 11b. At least a nearly C- or U-shaped bent part 11c-2 and a tongue piece 11c-3 extending to a forward end inside engaging surface 11b' of the body 11b are provided. And the part 11c-1 becomes a protective wall when the part 11c-2 elastically deforms, and by utilizing the form of the bent part 11c-2 and the contraction at the molding thereof, the tongue piece 11c-3 is located inside the surface 11b' of the body 11b from the beginning to effect molding. |
