Abstract

Abstract A unitary, flexible, and resilient clamp for applying clamping forces to the exterior surface of objects such as coolant hoses, tubes, or the like. The clamp has a generally arcuate cross-sectional configuration and includes a flexible band in the form of an open ring having opposed end portions and defining an inner arcuate portion. A first band end is connected to a first end portion of the flexible band and includes at least three inwardly projecting extensions. A second band end is connected to the opposite end portion of the flexible band and includes at least two extensions projecting inwardly towards the extensions of the first band end and configured to matingly engage therewith. The inwardly projecting extensions include correspondingly positioned pairs of mating teeth and are configured, positioned, and oriented such that when the band ends are moved towards each other the extensions become progressively matingly engaged with each other in a manner to maintain the clamp in a closed position such that the clamp assumes a cross-sectional shape corresponding to the cross-sectional configuration of the hose or object to be clamped and contacts its surface, providing uniformly distributed, stable and substantial clamping pressures.
