Abstract: A zipper lock contains a body, a locking cylinder, and a releasing element. The body has a locking mechanism disposed therein and at least one zipper locked thereon. The locking cylinder is defined on the body and is controlled by a key so as to change toward a lock position and a unlock position. The releasing element is mounted on the body for matching with the locking cylinder. Thereby, when the locking cylinder is changed toward the unlock position, it is moved toward a release position with the releasing element so as to remove the at least one zipper from the body.
