Size-indicating cable tie

1. A cable tie comprising:

a flexible strap comprising an elongated section defining a longitudinal axis and having a head end, a tail end, a top side and a lower side, the lower side defining a plurality of longitudinally spaced apart teeth extending transversely to the longitudinal axis;

a head defining a channel defined by side and top walls and adapted to receive the strap, an opening through which the strap is visible when the strap is engaged in the head, and a flexible pawl defining a plurality of longitudinally spaced, transversely extending teeth adapted to engage with one or more teeth of the strap, to retain the strap in the head; and

a series of visible markings spaced along the top side of the strap, where the visible markings are indicative of a diameter of the engaged tie, and at least one marking is visible through the head opening when the strap is engaged in the head.

2. The cable tie of claim 1 in which the visible markings comprise a series of numbers.

3. The cable tie of claim 2 in which the numbers are ascending, with the lowest number located closest to the head.

4. The cable tie of claim 1 in which the markings are arranged along the length of the top side of the strap beginning proximate the head end.

5. The cable tie of claim 4 in which the markings terminate before the tail end of the strap.

6. A cable tie comprising:

a flexible strap comprising an elongated section defining a longitudinal axis and having a head end, a tail end, a top side and a lower side, the lower side defining a plurality of longitudinally spaced apart teeth extending transversely to the longitudinal axis;

a head defining a channel defined by side and top walls and adapted to receive the strap, and a flexible pawl adapted to engage with one or more teeth of the strap, to retain the strap in the head; where the flexible pawl defines a plurality of longitudinally spaced, transversely extending teeth adapted to engage with one or more teeth of the strap; and

one or more visible markings on the top side of the strap, where the visible markings are indicative of a diameter of the engaged tie.

7. The cable tie of claim 6 in which the markings comprise numbers.

8. The cable tie of claim 7 in which the numbers are ascending, with the lowest number located closest to the head.

9. The cable tie of claim 6 in which the markings are arranged along the length of the top side of the strap beginning proximate the head end.

10. The cable tie of claim 9 in which the markings terminate before the tail end of the strap.

11. The cable tie of claim 6 where the visible markings are spaced along the top side of the strap.

12. A cable tie comprising:

a flexible strap comprising an elongated section defining a longitudinal axis and having a head end, a tail end, a top side and a lower side, the lower side defining a plurality of longitudinally spaced apart teeth extending transversely to the longitudinal axis;

a head defining a channel defined by side and top walls and adapted to receive the strap, an opening through which the strap is visible when the strap is engaged in the head, and a flexible pawl defining an upper surface comprising a plurality of longitudinally spaced, transversely extending teeth adapted to engage with one or more teeth of the strap, to retain the strap in the head; and

a series of visible markings spaced along the top side of the strap, where the visible markings are indicative of a diameter of the engaged tie and where at least one marking is visible through the head opening when the strap is engaged in the head.

13. The cable tie of claim 12 in which the markings comprise numbers.

14. The cable tie of claim 13 in which the numbers are ascending, with the lowest number located closest to the head.

15. The cable tie of claim 12 in which the markings are arranged along the length of the top side of the strap beginning proximate the head end.

16. The cable tie of claim 15 in which the markings terminate before the tail end of the strap.
