Abstract

The housing for the screw of a hose clip has a tubular section with a flat bottom wall a portion of which extends laterally beyond the tubular section and is overlapped by a plate-like second portion forming part of and being inclined with reference to a side wall of the tubular section. When the screw is rotated in a direction to tension the band which is placed around a hose, pipe or a like structure, the screw tends to move the extension toward such structure. The extension is or can be hollow to receive parts of the overlapping end portions of the band. Reinforcing ribs are provided at the outside of the housing between the side wall of the tubular section and the extension. The housing is made of a sheet metal blank which is deformed to form the tubular section and the two portions of the extension, and such portions of the extension are thereupon welded to each other.

Claims

1. In a clip wherein an elongated band having a threaded end portion and two marginal zones which flank said threaded end portion is adapted to be placed around a hose or a like structure, the combination of a housing having a substantially tubular section for said end portion of the band and a single lateral extension, said tubular section being nearer to one than to the other marginal zone and said extension being nearer to said other marginal zone of the band, said tubular section including a bottom wall forming part of said extension, and a tensioning element rotatably mounted in said tubular section and having external threads meshing with the threads of said end portion, said element being rotatable in a predetermined direction to thereby tension the band and said extension being urged toward the structure which is surrounded by the band when said element is rotated in said direction.

2. The combination of claim 1, wherein at least the major part of said bottom wall is substantially flat.

3. The combination of claim 1, wherein said tubular section further includes a side wall and said extension includes two substantially parallel plate-like components one of which forms part of said bottom wall and the other of which is integral with said side wall.

4. The combination of claim 3, wherein said other component and said side wall make an angle of less than 180 degrees.

5. The combination of claim 1, wherein said extension is hollow and the band includes two overlapping end portions extending in part into the interior of said extension.

6. The combination of claim 5, wherein said extension comprises two spaced-apart substantially parallel components and the distance between said components approximates the combined thickness of the end portions of the band.

7. The combination of claim 1, wherein said extension includes several components which are bonded to each other, one of said components constituting said part of said bottom wall and another of said components overlying said part of said bottom wall.

8. The combination of claim 7, wherein said components are welded to each other.

9. The combination of claim 1, wherein said housing further comprises reinforcing means interposed between said section and said extension.

10. The combination of claim 9, wherein said reinforcing means includes at least one rib which is integral with said section and said extension.

11. The combination of claim 1, wherein said tensioning element includes a shank having a predetermined diameter and the width of said extension, as considered at right angles to the axis of said shank, at least equals said diameter.

12. The combination of claim 11, wherein said housing consists of sheet metal.

13. The combination of claim 1, wherein said section of said housing has an end portion and said element includes an enlarged end portion abutting against the end portion of said section.
