Abstract
Abstract A hose clip which comprises a flexible strap adapted to be placed around a selected portion of a hose and to be tightened around such selected portion by turning a bolt or screw. An elongated concavo-convex strip-shaped resilient insert is adjacent a portion of the internal surface and extends in the circumferential direction of the strap opposite the mechanism which serves to increase or reduce the effective length of the strap. The convex external surface of the insert is biased in a direction away from the adjacent portion of the internal surface of the strap by one or more springs which are disposed between the insert and the strap and are of one piece with the insert. At least one end of the insert is slidable along the strap. The spring or springs ensure that the strap does not become loose as a result of aging of the material of the adjacent portion of the hose.
