Abstract: A closure for a closing strip includes a tooth strap (32) and a closure (1) with a guide for the tooth strap (32). In order to make it easy to separate the lock between the tooth strap and closure, the closure (1) has a meshing part (6,7) with a tooth and an unlocking part (16, 17), by means of which the tooth can be brought out of the meshed stage (FIG. 6).
