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.
