Holderless clamping hose

Abstract

A hose clamp comprises a clamp ring made of a metal strip rolled into a loop with its ends overlapping each other. First and second pinches are projected up from the ends of the metal strip in the radial direction. The first pinch has a frame, which defines an opening inside the frame, and a stopper wall swelling into the inside opening from a corner of the frame. The second pinch has an operation chip extending in the width direction of the cram ring. A stopper rises from the clamp ring near the root of the second pinch. The hose clamp has a clamping position, at which the first and second pinches are apart from each other, and a loosened position, at which the first and second pinches are very close to each other. At the loosened position, the operation chip of the second pinch sticks out from the clamp ring in the width direction of the clamp ring.
