Patent ID: 8689407

Claim:
A hose clamp comprising: a clamp body having a plurality of screw holes passing therethrough; a coupling housing which is disposed at one side of the clamp body and into which an opposite side of the clamp body is inserted; and a coupling screw rotatably disposed in the coupling housing and engaged with the screw holes of the clamp body inserted within the coupling housing, wherein the clamp body comprises a compensating means including at least one compensation bead formed at one side of the clamp body for resiliently fastening a hose by a degree by which a diameter of the hose is decreased so as to firmly tighten the hose, wherein the hose clamp further comprises a plastic deformation prevention means for preventing the compensation bead from being plastically deformed and the hose from penetrating between the clamping body and the coupling housing or into the screw holes and thus being damaged, wherein the plastic deformation prevention means comprises: a circular arc-shaped prevention band having a size large enough to cover and contact the screw holes of the clamp body, a recess formed between the clamp body and the coupling housing, and the compensation bead, a pair of fixing pins formed at one side of the compensation bead on the prevention band, and a pair of guide pins formed at the other side of the compensation bead on the prevention band, and wherein the clamp body further comprises a pair of fixing pin holes formed at positions corresponding to the fixing pins and into which the fixing pins are inserted and a pair of guide holes formed at positions corresponding to the guide pins and into which the guide pins are inserted.
