ABSTRACT:
In an auto-lock slider for a slide fastener, each of front and rear attachment lugs on a slider by has a provisional spring-holding ends in the form of a holding projection having in its top a V-shape groove, each lug having on opposite side surfaces a pair of guides and in its outer side base a pair of recesses. In assembly, a leaf spring having in its each end a cutout is placed on the two holding projections, whereupon these projections are clenched, by pressing, to provisionally hold the spring. At that time, a locking lever is supported on e slider body between the lugs to normally urge the locking lever to a slider locking position, and a pintle of a pull tab is disposed between the locking lever and the slider body for bringing the locking lever out of the slider locking position against the resilience of the leaf spring. Finally, the lugs, the spring, the pintle of the pull tab and part of the locking lever on the slider body are covered by a cover of which side walls are clenched against the four recesses of the lugs.
