Cable ties, also known as zip ties or wire ties, are fastening devices used to secure and organize cables, wires, hoses, and other items. They consist of a flexible strap with teeth on one end and a ratchet mechanism on the other. To use a cable tie, the strap is passed through the locking mechanism, and then tightened around the items to be secured. The teeth on the strap engage with the ratchet mechanism, preventing the tie from loosening once tightened.
