A worm drive clip comprises a housing having a driving worm screw inserted therein, with the housing comprising an upper part and a bottom part for enclosing the worm screw and a flexible band with transverse ribs and transverse openings inserted in the housing. The band has transverse ribs and transverse openings equally spaced along its full length. The bottom part of the housing has means engageable with at least one transverse rib and/or at least one transverse opening of the band at one end of the band. The worm screw is engageable with the transverse ribs and the transverse openings at the other end of the band. Thereby a worm drive clip is obtained with a housing which is easy to fasten to a perforated band in situ, where it is desired to use the band with the housing of the worm drive clip, whereby a length of band, which is a little longer than the periphery of a hose, may be cut off for clamping on the hose of an arbitrary diameter, whereupon the housing of the worm drive clip may be mounted on the band piece for clamping the hose.
