Retained tension multiple ball lock cable tie

1. A cable tie comprising:

an elongate metallic strap, the elongate metallic strap having a first end, a second end and a width, the second end being disposed opposite the first end;

a metallic locking head, the metallic locking head being secured to the first end of the elongate metallic strap, the metallic locking head being adapted to receive the second end of the elongate metallic strap, the metallic locking head having a floor, a roof, and at least one retention means, wherein the metallic locking head defines an open area from the at least one retention means to a strap exit face;

at least two metallic roller means, each of the metallic roller means being adapted to lockingly engage the elongate metallic strap;

at least three protuberances, wherein each of the at least three protuberances are aligned and equidistantly spaced along the width of the strap, each of the protuberances being disposed on the elongated metallic strap proximate the strap exit face of the locking head, wherein one of the protuberances being aligned with a center line of the strap and positioned in the open area of the locking head;

wherein the combination of each of the roller means and each of the protuberances increases the tension in the elongate metallic strap.

2. The cable tie of claim 1 , wherein the metallic locking head comprises a strap entry face.

3. The cable tie of claim 2 , wherein the metallic locking head further comprises a strap receiving aperture extending between the strap entry face and the strap exit face.

4. The cable tie of claim 1 , wherein the at least one retention means comprises at least one finger, each of the at least one finger extending from the roof adjacent the strap exit face.

5. The cable tie of claim 4 , wherein the retention means is disposed adjacent to the strap exit face, the retention means adapted to captively hold the metallic roller means within the metallic locking head.

6. The cable tie of claim 1 , wherein the metallic roller means is movable between a first threading position and a first locking position.

7. The cable tie of claim 6 , wherein the first threading position is where the metallic roller means is disposed adjacent the strap exit face and the retention locking means.

8. The cable tie of claim 7 , wherein the first locking position is where the metallic roller means is closer to the strap entry face.

9. The cable tie of claim 1 , wherein a first protuberance is disposed between a first metallic roller means and a first sidewall of the metallic locking head.

10. The cable tie of claim 9 , wherein a second protuberance is disposed between the first metallic roller means and a second metallic roller means.

11. The cable tie of claim 10 , wherein a third protuberance is disposed between the second metallic roller means and a second sidewall of the metallic locking head.

12. The cable tie of claim 1 , wherein the floor and the roof both diverge in the direction of the strap exit face.

13. The cable tie of claim 1 , wherein the elongate metallic strap is comprised of stainless steel.

14. The cable tie of claim 1 , wherein the elongate metallic locking head is comprised of stainless steel.

15. The cable tie of claim 1 , wherein the elongate metallic locking head further comprises at least two side walls.

16. The cable tie of claim 1 , wherein the second end of the elongate metallic strap is threaded through the locking head to engage the roller means, whereby after the elongate metallic strap has been tightened and the roller means are in a locked position, the elongate metallic strap engages the protuberances further retaining the tension in the cable tie.
