Abstract
Abstract A three part interlocking tangential worm driven clamp in which the desired size of the clamp is selectively formed by a length of band material having a series of spaced openings therein. A worm and housing unit is interlocked with one end of the band by means of the band openings and a slotted take up member is coupled to the opposite end of the band.
