Slider for slide fastener
 In a slider for a slide fastener, front and rear attachment lugs are arranged on the upper surface of an upper wing of a slider body, each having a horizontal insertion hole and an arcuate guide surface contiguous to the insertion hole. A pull tab retaining bar has a length so as to bridge over the front and rear attachment lugs and has a pair of taper legs one on each end. For assembly, with a pintle of a pull tab placed between the two attachment lugs, the legs are forced into the insertion holes along the guide surfaces as they deform prastically, securing the pull tab retaining bar to the attachment lugs. Accordingly, the pull tab retaining bar can be attached to the slider body simply by pressing from the upper side, thus facilitating automatic assembling.
