<p>Provided is a hose clamp that is able to prevent the occurrence of a leak channel when fastening a hose. The hose clamp (10) is provided with: a clamp main body (12) formed by curving a strip-shaped leaf-spring material into an annular shape; and a pair of operation pieces (13, 21). The clamp main body (12) is held in an expanded-diameter state by means of a locking claw (14) towards the side of one operation piece (13) engaging an engagement concavity (22) towards the side of the other operation piece (21) of the clamp main body (12). The clamp main body (12) contracts from the expanded-diameter state by means of the engagement of the locking claw (14) with the engagement concavity (22) being released by means of causing the one operation piece (13) to approach the other operation piece (21) and to move in the direction of reciprocation along the axial direction of the clamp main body (12). A leak prevention piece (28) that presses the hose (32) and nearly contacts the end on the one operation piece (13) side during hose (32) fastening is provided to the end on the other operation piece (21) side of the clamp main body (12)</p> |
