Title:
HOSE CLAMP
Document Type and Number:
WIPO Patent Application WO/2012/095990
Kind Code:
A1
Abstract:
Provided is a hose clamp that can prevent the occurrence of a leak channel when fastening a hose. The hose clamp (10) is provided with: a clamp main body (12) that is formed by bending a band-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) to the engagement concavity (22) being released by 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). The other operation piece (21) is provided with an expansion-restricting piece (24) that restricts the expansion of both operation pieces (13, 21) in the direction of reciprocation along the axial direction of the clamp main body (12) by contacting the locking claw (14) when releasing the engagement of the locking claw (14) to the engagement concavity (22).
