ABSTRACT:
A hose clip wherein the housing is made of an originally flat sheet metal blank and has a tubular section for the shank of a rotary screw mating with one end portion of a band whose end portions extend through the tubular section between the thread on the shank and a flat bottom wall of the tubular section. The head of the screw has a tubular portion which surrounds one end portion of the tubular section so as to hold such end portion against radial and/or axial movement relative to the screw whereby the head cannot penetrate into and cannot expand the tubular section while it rotates in a direction to tension the band around the end portion of a hose or an analogous structure. The tubular portion may be integral with the remaining portion of the head, it can be bonded to such remaining portion or it may be rotatably mounted on the shank adjacent to the remaining portion of the head. Since the head cannot penetrate into the housing and the screw cannot pivot with reference to the housing, the shank of the screw can apply to the band a very pronounced tensional stress to tighten the looped intermediate portion of the band around a hose or the like. An extension of the housing which is disposed substantially radially or tangentially of the shank is provided to prevent tilting of the housing as a result of rotation of the tubular section with the shank when the screw is rotated in a direction to tension the band. Teeth between two neighboring surfaces of the tubular section and the head reduce the likelihood of excessive tensioning of the band in that the teeth oppose continuous rotation of the shank by causing the head to ratchet with respect to the adjacent end portion of the tubular section. The teeth can also prevent or oppose rotation of the screw in a direction to reduce the tensional stress upon the band.
