Tamper-evident attachment for cable tie

1. A tamper-evident attachment for a cable tie of the type including a ratchet head defining a head opening and having a deflectable pawl in the head opening, and a flexible strap extending from the ratchet head, the tamper-evident attachment comprising:

a ratchet head cover configured to couple to the ratchet head of the cable tie such that the ratchet head cover covers at least a portion of the head opening to inhibit access to the pawl, the ratchet head cover defining at least one slot-shaped opening positioned to align with the head opening of the ratchet head when the ratchet head cover is coupled to the ratchet head, the at least one slot-shaped opening being sized and shaped to receive the strap of the cable tie therethrough, wherein the ratchet head cover further includes a left wall, a right wall generally opposing the left wall, a rear wall extending between and connecting the left and right walls, and an upper wall interconnecting upper ends of the left wall, right wall, and rear wall.

2. The tamper-evident attachment of claim 1 , wherein the at least one slot-shaped opening includes two slot-shaped openings positioned to align on either side of the head opening of the ratchet head such that the strap can extend through the two slot-shaped openings and the head opening when the ratchet head cover is coupled to the ratchet head.

3. The tamper-evident attachment of claim 1 , wherein the at least one slot-shaped opening is sized and shaped to be in a close fitting relationship with the strap of the cable tie when the strap is received in the at least one slot-shaped opening to inhibit access to the pawl of the cable tie.

4. The tamper-evident attachment of claim 1 , wherein the left, right, rear, and upper walls ratchet head cover define a cavity configured to receive the ratchet head of the cable tie.

5. The tamper-evident attachment of claim 4 , wherein the ratchet head cover further defines a front opening in communication with the cavity, the front opening sized and shaped to allow the ratchet head of the cable tie to be inserted therethrough to be positioned in the cavity.

6. The tamper-evident attachment of claim 5 , wherein the ratchet head cover further defines a bottom opening in communication with the cavity and the front opening, the bottom opening sized and shaped to receive the strap of the cable tie therethrough when the ratchet head cover is coupled to the ratchet head.

7. The tamper-evident attachment of claim 1 , wherein the ratchet head cover further includes a detent configured to engage the cable tie to hold the ratchet head cover on the ratchet head of the cable tie when the ratchet head cover is coupled to the ratchet head.

8. The tamper-evident attachment of claim 7 , wherein the detent engages the strap of the cable tie to hold the ratchet head cover on the ratchet head.

9. The tamper evident attachment of claim 1 , wherein the left wall, right wall, rear wall, and upper wall each have an interior surface, the interior surfaces defining a cavity sized and shaped to receive the ratchet head of the cable tie.

10. The tamper-evident attachment of claim 1 , wherein at least one of the right and left walls defines the at least one slot-shaped opening.

11. A tamper-evident security seal comprising:

a cable tie including

a ratchet head defining a head opening and including a deflectable pawl in the head opening, and

a flexible strap extending from the ratchet head; and

a tamper-evident attachment coupled to the ratchet head of the cable tie and covering at least a portion of the head opening to inhibit access to the pawl, the tamper-evident attachment defining at least one slot-shaped opening aligned with the head opening of the ratchet head that is sized and shaped to receive the strap of the cable tie therethrough, wherein the tamper-evident attachment includes a detent engaging the cable tie and holding the tamper evident attachment on the ratchet head of the cable tie before the strap of the cable tie is received through the at least one slot-shaped opening and the head opening of the ratchet head.

12. The tamper-evident security seal of claim 11 , wherein the at least one slot-shaped opening includes two slot-shaped openings positioned to align on either side of the head opening of the ratchet head such that the strap can extend through the two slot-shaped openings and the head opening when the tamper-evident attachment is coupled to the ratchet head.

13. The tamper-evident security seal of claim 11 , wherein the tamper-evident attachment further defines a cavity, the ratchet head of the cable tie being positioned in the cavity.

14. The tamper-evident security seal of claim 11 , wherein the tamper-evident attachment is integrally formed with the ratchet head of the cable tie.

15. A tamper-evident attachment for a cable tie of the type including a ratchet head defining a head opening and having a deflectable pawl in the head opening, and a flexible strap extending from the ratchet head, the tamper-evident attachment comprising:

a ratchet head cover configured to couple to the ratchet head of the cable tie such that the ratchet head cover covers at least a portion of the head opening to inhibit access to the pawl, the ratchet head cover defining at least one slot-shaped opening positioned to align with the head opening of the ratchet head when the ratchet head cover is coupled to the ratchet head, the at least one slot-shaped opening being sized and shaped to receive the strap of the cable tie therethrough,

wherein the ratchet head cover includes a detent configured to engage the cable tie to hold the ratchet head cover on the ratchet head of the cable tie before the strap of the cable tie is received through the at least one slot-shaped opening and the head opening of the ratchet head.

16. The tamper-evident attachment of claim 15 , wherein the at least one slot-shaped opening includes two slot-shaped openings positioned to align on either side of the head opening of the ratchet head such that the strap can extend through the two slot-shaped openings and the head opening when the ratchet head cover is coupled to the ratchet head.

17. The tamper-evident attachment of claim 15 , wherein the at least one slot-shaped opening is sized and shaped to be in a close fitting relationship with the strap of the cable tie when the strap is received in the at least one slot-shaped opening to inhibit access to the pawl of the cable tie.

18. The tamper-evident attachment of claim 15 , wherein the ratchet head cover further defines a cavity configured to receive the ratchet head of the cable tie.
