Abstract

The invention relates to a hose clamp (1) with a clamp body (3) which encloses a hose end (2) essentially in a ring with overlapping end areas (4,5). In the clamped state, the clamp body has an initial diameter, and using a clamping tool, the clamp body (3) can be spread to a second, larger diameter against its own spring force. In a first end area (4), there is a catch projection (6) which is offset rearward relative to its outer front edge (7) and which can be engaged with a second end area (5) of the clamp body (3) to achieve the spread state. The second end area (5) has a longitudinally extended recess (8) which holds first end area (4) which is correspondingly narrower. To be able to easily spread and release hose clamp (1), in a way which enables the attainment of the spread state is to be easily recognizable, a catch projection (6) is provided on the first end area (4,) in the spread state of the clamp body, rests against the front edge (10) of the second end area (5).
