Abstract: A zipper slide with means for restraining a pull tab thereof from swinging is provided. The zipper slide is composed of a slide and a pull tab. The pull tab includes a tab portion and a U-shaped buckle connected to a rear end of the tab portion. The slide is formed of a central passage for the U-shaped buckle to extend therethrough and be fixed thereto. An elastic projection axially extends from the rear end of the tab portion, and the slide is formed at a top front with a hollow space into which the elastic projection extends when the tab portion is in a flat position relative to the slide. When the tab portion is pivotally turned upward relative to the slide, the elastic projection is brought into contact with a front edge of the hollow space, and a further pull would deform the elastic projection to bring the same to move out of the hollow space for moving the slide forward or backward.
