Abstract: A device for holding hose clamps in a predetermined position, wherein the hose clamps each have a clamping part projecting radially away from a circumference of the hose clamps and wherein the clamping part has a projection extending in the circumferential direction, has a rail having a longitudinal slot for receiving the clamping part of the hose clamps via an open end of the longitudinal slot. The longitudinal slot has an edge configured to support the projection. The rail is a tube having an inner side projecting inwardly into a corner formed between the projection and an outer end section of the clamping part adjoining the projection.

Abstract: A hose clamp for clamping a hose on a pipe has a spring band bent to a ring-shape and end sections that positively lock one another in a locking position when the spring band is in a spread-apart position widened past a nominal diameter of a hose against a spring force of the spring band. The locking position of the end sections is releasable such that the spring band contracts about the hose. The end sections are positioned laterally adjacent to one another in an axial direction of the hose clamp and have a first edge and a second edge facing one another in the axial direction of the hose clamp. The first and second edges have at least one laterally projecting tooth, respectively.
