Abstract: The adjustable band clamp includes a single, elongated, narrow width band of metal having at one end thereof a plurality of cut-out windows. A crimpible, protruding band region is disposed immediately inboard the plurality of windows. Preferably, the crimpible protruding band region is a raised, U-shaped region having a central depression on its raised platform portion. At the other end of the band and disposed at predetermined longitudinal intervals over the substantial length of the band, a plurality of groups of protruding ears or extending notch fingers rise above the outer surface of the band. In operation, one or more ears from a simple group of longitudinally spaced apart ear sets are locked into the cut-out window.

Abstract: A split boot formed from a unitary, flexible body shaped to be helically wrapped around a universal joint or the like. Once the flexible body is wrapped around the joint with the mating edges engaged a main body is formed having a generally hollow truncated conical configuration with a corrugated or helical shape. One end of the main body has a smaller circular cross section than the other end. Each end portion of the main body has cutting guide ridges such that the diameter of the aperture in the end may be varied by removing some of the material from the body.
