Abstract

The invention relates to a hose clip with a bearing part for a band tightening screw, a metal housing with a bracket and an annularly curved flat metal band. At one end the metal band is rigidly secured to the bracket and its other free end can be led through a band channel in the housing close to the bracket. In addition, in the region of its free end, the metal band has a grid-like set of perforations with transversely inclined shoulders to engage with a short thread on the tightening screw in the bracket region of the housing. To permit automatic manufacture with a high degree of process reliability, the housing takes the form of a one-piece bent component attached by laser weld seams at joining points in the region of the bearing part and the saddle. In addition, one end of the band is either butt or lap-welded to the bracket by another laser weld seam. The band tightening screw is arranged axially and radially in the bearing part with a head section and, at the end opposite the head section has a short thread. The short thread can be fully axially moved out of its region of engagement with the band perforation, thus permitting rapid fitting.

Dependent claims

A hose clip, comprising:

a band-tightening screw having a threaded portion;
a metallic housing having a bearing part for rotatably supporting said band-tightening screw, and a saddle which includes wall means having an interior surface defining a band channel in said housing, an exterior clamping surface adapted for contact with a hose being clamped, and first and second saddle edges disposed at opposite ends of said band channel, said band channel opening toward the threaded portion of said screw and having at least a first aperture proximate said first saddle edge, said housing being a bent stamped metal part which is joined at joints disposed in the area of at least one of said bearing part, said saddle and said second saddle edge thereof;
and
an annularly curved flat metal band having first and second band ends, a radially inward facing surface and a radially outward facing surface, said band having a grid-like sequence of slots with transversely oriented shoulders disposed proximate said first band end, said second band end butting against said second saddle edge and being rigidly connected thereto with said radially inward facing surface of said band being substantially flush with said exterior clamping surface of said saddle, said first band end being guided within said band channel through said first aperture and disposed with said slots operatively engaging said threaded portion to facilitate clamping of a hose upon rotation of said screw.
