HOSE CLAMP

PROBLEM TO BE SOLVED: To provide a hose clamp that can prevent the damage and deformation of a fastening housing while securing a sufficient fastening force.SOLUTION: The hose clamp includes a clamp body, a screw, a piercing hole, and correction beads which fasten the hose in a rigid state by elasticity as the hose is contracted in diameter, and further includes a plastic deformation prevention means which prevents that the correction beads cannot be returned to original states due to an effect that the correction beads are plastically deformed and lose elasticity. The plastic deformation prevention means has a prevention body which communicatively contacts with the inner surface of the clamp body in which the correction beads are formed, one end of the prevention body is fixed to the clamp body by a fixing means, stop pins of the number equal to that of the correction beads are formed at the prevention body located in an opposite position fixed to the fixing means, the stop pins are connected to the correction beads and stop holes which are formed between the stop beads, and thus the correction beads are limited in being plastically deformed at fastening.
