A cable tie or tie-wrap is a type of fastener for holding items together, primarily electric cables or wires. Tie wraps are relatively cheap and easy to use.

The tie-wrap is normally made of nylon and has a tape section with teeth that engage with a pawl in the head to form a ratchet. As the free end of the tape section is pulled the tie-wrap tightens and does not come undone.

Another version of the tie-wrap allows a tab to be depressed to either adjust the tension or remove the tie-wrap. Even regular tie wraps could anyway be untightened using a needle.
