ABSTRACT:
This invention relates to a hose clamp constituted by a band of material, generally metal, wound on itself, one of the ends of said band presenting relief elements forming a rack, whilst on the other end is fixed a housing which constitutes the support of a screw which is mounted to pivot about its axis, said screw abutting on a stop axially mobile with respect to the housing against the action of a spring. The spring is constituted by a curved blade, for example in the form of a semi-circle, whose concavity faces the inside of the clamp and whose ends are laterally in contact with the sides of the housing. A first end of said blade is axially fixed to the housing and provided with an opening in which the tail of the screw may slide, whilst the second end of the blade surrounds at least partially the shank of the screw in the vicinity of its head and is mounted to slide with respect to the sides of the housing.
