Abstract
A plastic reclosable fastener or zipper with slider detent lock for locking the slider in closed position on plastic-film bags and the like is disclosed. The slider includes two spring-loaded detent elements located on opposite sides of the separator finger on the slider. When the slider is at any location other than the fully closed position at the end of the fastener, the spring-loaded detent elements ride against the outside surfaces of the flanges by which the separator finger opens the fastener. When the slider reaches the location at the end of the fastener where portions of the flanges have been removed to provide a notch, the spring-loaded detent elements spring inward against the sides of the separator finger. There they resist an attempt to move the slider in an opening direction because this requires that they be forced outward over the flanges of the zipper.
