Abstract
A hose clamp for preventing a leak during tightening of a hose includes a clamp body with a strip-shaped leaf spring having an annular shape, and a pair of operation pieces. The clamp body maintained in a diameter expansion state by a locking claw of the operation piece engaged with an engagement concavity of the operation piece of the clamp body. The locking claw is released by bringing the operation piece on one side close to the operation piece on the other side and moving the operation piece on one side with respect to the operation piece on the other side in the opposing direction in an axial direction of the clamp body, reducing the clamp body in diameter. A leak prevention piece presses a hose during tightening of the hose at an end portion of the operation piece on the other side of the clamp body.
