Cable tie

Abstract

Disclosed in the present invention is a cable tie. The cable tie includes a locking head and a tie body, where one end of the tie body is fixedly connected to an outer wall of one end of the locking head close to an extend-in opening, tie teeth are fixedly arranged on outer walls of two sides of the tie body, locking teeth are mounted on inner walls of two sides of the locking head, the locking teeth are matched with the tie teeth, and an extend-out head is integrally formed at one end of the tie body away from the locking head. Engagement on the two sides can prevent the teeth from being reversed when the tie body is pulled. The stress of the locking teeth on the two sides is reduced, resulting in the concentrated force on individual tooth, thereby preventing the teeth from being broken.
