Abstract

A system for pre-positioning a hose clamp (2) on a hose end (24) includes: a) a fixing part (1′) which is connected non-releasably to an annular segment of the hose clamp (2) and is fastened to the hose end (24), and b) one or more fixing parts (1, 1″) which each have a U-shaped element which, fastened to the hose end (24), is directed with its open side (3) to the hose surface. The web (6) connects the two U-legs (4, 5) and extends axially and parallel to the hose surface. The U-leg (4), which lies closest to the hose end (24), has a connecting element (7) for attaching the U-shaped element to the end face of the hose end (24). The U-shaped element is configured in such a way that the hose clamp (2), which is pulled on to the hose end (24), is fixed releasably in the intermediate space (8) of the U-shaped element by way of an annular segment of the hose clamp in such a way that the hose clamp (2) is released from the fixing when tightened. The fixing part (1) remains without function on the hose end (24) after the hose clamp (2) has been tightened.
