A boot band where resistance that a band body receives as it rides over an engagement claw when it is tightened is reduced, by which the band body can be tightened with small tightening force. The boot band has a band body (31) wound and tightened around a member to be tightened, with an outer superposing section (32) and an inner super posing section (33) superposed over each other in a ring form; engagement claws (36, 37) formed at the outer superposing section (32); engagement holes (34, 35) formed in the inner superposing section (33) and keeping the band body (31) in a tightened state by engaging with the engagement claws (36, 37); a lip section (43) formed by separating an engagement hole forming region, which is in the inner superposing section (33), from its periphery in a tightening direction (S) of the band body (31) and formed such that the tip side of the lip section in the tightening direction is a free end (43a); and a slit (44) formed near the engagement claws at the outer superposing section (32) and through which the lip section (43) penetrates and comes out.
L~invention concerne un collier pour soufflet dont le corps offre moins de résistance lorsqu~il passe sur des mâchoires d~engagement, ce qui permet de serrer celui-ci par une faible force de serrage. Le collier pour soufflet comporte un corps (31) de collier monté et serré autour d~un élément à serrer, une partie de superposition extérieure (32) et une partie de superposition intérieure (33) se superposant pour former un anneau ; des mâchoires d~engagement (36, 37) formées au niveau de la partie de superposition extérieure (32) ; des trous d~engagement (34, 35) formés dans la partie de superposition intérieure (33) et maintenant le corps (31) de collier serré en engageant les mâchoires d~engagement (36, 37) ; une partie de rebord (43) formée par séparation d~une région dans laquelle sont formés les trous d~engagement, autrement dit la partie de superposition intérieure (33), de sa périphérie dans la direction de serrage (S) du corps (31) de collier et de telle sorte que le bout de la partie de rebord dans la direction de serrage forme une extrémité libre (43a) ; et une fente (44) formée à proximité des mâchoires d~engagement au niveau de la partie de superposition extérieure (32) et à travers laquelle la partie de rebord (43) passe et sort.
