PCT No. PCT/EP92/00788 Sec. 371 Date Apr. 1, 1994 Sec. 102(e) Date Apr. 1, 1994 PCT Filed Apr. 7, 1992 PCT Pub. No. WO92/20950 PCT Pub. Date Nov. 26, 1992.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. |
