Hose clamp

Abstract

In a hose clamp having a resilient clamp body (2) substantially annularly surrounding one hose end and having tightening ends (6, 7) that overlap one another and are bent substantially radially away from the clamp body (2), in which a certain inside diameter prevails in the relaxed state, and the clamp body (2) can be spread apart to a considerably greater diameter counter to its own spring force with the aid of a tightening tool engaging the tightening ends (6, 7), and one tightening end (6) is embodied as an inverted U and the other tightening end (7) is embodied in protrusionlike fashion and is disposed between the U legs of one tightening end (6) with its free end approximately at the radial height of the crossbar of the U of the one tightening end (6), and the one tightening end (6), for forming a shackle (8), is bent back toward the other tightening end (7) substantially at a tangent or in a circumferentially curved manner, at a certain radial distance from the clamp body (2), and the tightening ends (6, 7) in the spread-apart state of the clamp body (2) are interlocked with one another and for clamping a hose end are unlocked from one another, the danger of unintentional unlocking is reduced, yet intentional unlocking is still easily attainable, by providing that the shackle (8) at the free end of the one tightening end (6) is bent at the end as a detent hook (9) radially inward onto the clamp body (2), and in the spread-apart state grips the free end of the other tightening end (7) lockingly from behind.
