Abstract

A fastener for holding tubes, fluid lines and the like is provided with a barb for deforming material on the surface of tubular fluid line held in the fastener, and a hollow adjacent the barb for receiving the deformed material.

Claims

1. A fastener for holding an object, said fastener comprising:

an anchoring part for securing the fastener in an assembly;

a holding part forming a pocket for capturing the object therein;

a projection extending into the pocket, said projection configured to deform surface material of the object held in the pocket upon rotation of the object in the pocket; and

a hollow adjacent the projection and positioned to receive the deformed material of the object as deformed by the projection upon rotation of the object in the pocket.

2. The fastener of claim 1, said projection comprising a barb.

3. The fastener of claim 1, including a plurality of said projections and a hollow adjacent each said projection.

4. The fastener of claim 3, said projections distributed on opposite sides of said pocket and said fastener including at least first and second hollows, one on each side of said pocket.

5. The fastener of claim 1, said holding part including first and second pockets, first and second projections extending into said first and second pockets, and first and second hollows adjacent said first and second projections.

6. The fastener of claim 5, said first and second projections comprising first and second barbs.

7. The fastener of claim 5, each of said first and second pockets including a plurality of said projections and a plurality of said hollows.

8. A tube assembly, comprising:

a tube having exposed surface material; and

a fastener capturing the tube, said fastener including;

an anchoring part for securing the fastener to an object;

a holding part forming a pocket for capturing the tube therein;

a projection extending into the pocket, said projection configured to deform the tube held in the pocket upon rotation of the tube; and

a hollow adjacent the projection and positioned to receive deformed material of the tube as deformed by the projection upon rotation of the tube in the pocket.

9. The assembly of claim 8, said tube including a cylinder and a coating on the cylinder, said coating being of sufficiently malleable material to be deformed by said projection upon rotation of said tube in said pocket.

10. The assembly of claim 8, said projection comprising a barb.

11. The assembly of claim 10, said tube including a cylinder and a coating on the cylinder, said coating being of sufficiently malleable material to be deformed by said barb upon rotation of said tube in said pocket.

12. The assembly of claim 8, said fastener including at least first and second projections on opposite sides of said pocket, and first and second hollows adjacent said first and second projections.

13. The assembly of claim 12, said tube including a cylinder and a coating on the cylinder, said coating being of sufficiently malleable material to be deformed by said projections upon rotation of said tube in said pocket.

14. The assembly of claim 8, said holding part defining a second pocket having a second projection extending into the second pocket and a second hollow disposed adjacent the second projection.

15. The assembly of claim 8, said pocket having a bottom and first and second arms extending from said bottom in opposed spaced relation, said projection and said a hollow disposed on one of said first and second arms, a second projection being a barb projecting into said pocket from the other of said first and second arms and a second hollow disposed adjacent said barb.

16. A tube fastener holding a tube, the tube having a malleable material exposed on the surface thereof, said tube fastener comprising:

an anchoring part for securing the tube fastener in an assembly;

a holding part forming a pocket for capturing the tube therein;

a barb extending into the pocket, said barb configured to deform the malleable material exposed on the surface of the tube upon rotation of the tube in the pocket; and

a hollow adjacent the barb and positioned to receive a deformed portion of the malleable material as deformed by the barb upon rotation of the tube in the pocket.

17. The tube fastener of claim 16, said pocket including a bottom and opposed first and second arms, said barb disposed on one of said first and second arms along with said hollow, the other of said first and second arms including a protrusion extending into the pocket and a second hollow disposed adjacent the protrusion.

18. The tube fastener of claim 17, said holding part defining a second pocket having a second barb extending into the second pocket and a third hollow disposed adjacent the second barb.

19. The tube fastener of claim 16, said holding part defining a second pocket having a second barb extending into the second pocket and a second hollow disposed adjacent the second barb.

20. The tube fastener of claim 16, said hollow containing a deformed portion of the malleable material.
