Abstract
Abstract A device for clamping a hose end section that is fitted onto a pipe end section includes a hose clamp surrounding a hose end section. The hose clamp has overlapping end sections, each of which has an approximately radially outwardly extending tensioning jaw. A securing ring is fixed to the hose end section and has a radial projection. The securing ring surrounds the hose end section and is disposed between the hose end and the hose clamp. The securing ring is joined to the hose clamp in an area diametrically opposite to the area of overlap of the end sections of the hose clamp. The securing ring has a recess disposed in a radial projection. An approximately U-shaped clip has a cross-piece and a pair of legs depending from the cross-piece. The U-shaped clip is disposed such that, in the tensioned state, the legs of the clip overlap the tensioning jaws of each of the end sections. The U-shaped clip has a hook depending from the cross-piece that is radially engaged in the recess. In a further embodiment, the securing ring is not utilized and the cross-piece has an edge extending in the peripheral direction of the hose clamp. The edge is disposed on the free end side of the cross-piece and has a supporting arm depending from the edge such that, in the tensioned state, the supporting arm rests on the hose.
