Abstract
Abstract A worm drive hose clip comprises a housing, a band having one end secured to the housing and the other end passed through the housing, and a screw which is effectively journalled in the housing and held axially captive therein. Teeth are formed on one face of the band for engagement with the screw, each of which has a crest which is concave along a central portion of its length extending transversely of the band. The root-to-crest height of the central portion of each tooth increases toward each end of said central portion of the crest.
