Clip for securing around a member such as a pipe

摘要

Clips are known in which a worm wheel is meshed with teeth provided on an end portion of a band for encircling the member to be clamped, but such clips are relatively costly to produce and problems arise in maintaining the band threads meshed with the worm. Various clips are described in which an end portion of the band is provided on one side with external screw thread portions which are complementary to the internal screw threads of a nut through which the band end portion extends. The opposite end of the band may be integral with a body on which the nut is supported, or it may be identical to the first end portion also be meshed with the nut threads, so that both end portions of the band are drawn through the nut on turning of the nut.
