Abstract

A clamp with a first clamp halve with a hinge portion and a first opening for a fastener; a second clamp halve, with a hinge portion and a first opening for a fastener; a cable opening; and a hinge device for connecting the two hinge portions. The clamp may also include a first clamp halve with a second opening for a closing insert.

Claims

1. A clamp for a cable comprising:

a first clamp halve with a hinge portion and a first opening for a fastener;

a second clamp halve;

with a hinge portion and a first opening for a fastener;

a cable opening;

and a hinge device for connecting the two hinge portions.

2. The clamp of claim 1, further comprising a fastener, wherein said fastener is inserted in said fastening openings and said fastener tightens said clamp.

3. The clamp of claim 1, wherein said first and second clamp halves further comprise a bushing.

4. The clamp of claim 1, wherein the hinge portions are above said cable opening and said fastener is below said cable opening.

5. A clamp for a cable comprising:

a first clamp halve with a hinge portion, a first opening for a fastener; and

a second opening for a closing insert;

a second clamp halve;

with a hinge portion and a first opening for a fastener;

a cable opening;

and a hinge device for connecting the two hinge portions.

6. The clamp of claim 5, further comprising a closing insert that is inserted in said closing insert opening, wherein said closing insert causes said clamp to close.

7. The clamp of claim 5, further comprising a fastener, wherein said fastener is inserted in said fastening openings and said fastener tightens said clamp.

8. The clamp of claim 5, wherein said first and second clamp halves further comprise a bushing.

9. The clamp of claim 5, wherein the hinge portions are above said cable opening and said fastener is below said cable opening.

10. The clamp of claim 5, wherein the hinge portions are above said cable opening;

said fastener is below said cable opening and said closing insert is above said hinge portions.

11. The clamp of claim 5, wherein the closing insert comprises a thumbscrew.

12. The clamp of claim 5, wherein the closing insert comprises an eyehook.

13. A method of attaching a clamp to a cable comprising:

opening said clamp;

placing said clamp over a cable;

closing said clamp;

tightening said clamp with a fastener.

14. The method of claim 13 wherein

said clamp is opened by moving top portions of clamp halves close together;

and

said clamp is closed by moving bottom portions of said clamp halves together.

15. The method of claim 13 wherein said clamp is closed by inserting a closing insert.

16. The method of claim 15 wherein an attaching device is used to insert said closing insert and close said clamp.

17. The method of claim 16 wherein said attaching device is used to remove said closing insert after said clamp is tightened.
