A slide fastener slider comprises a slider body including a pair of upper and lower wings defining therebetween a Y-shaped guide channel, the lower wing having a pair of lateral flanges and a pair of corner ledges, each extending along an inner face of the respective flange through its length. The slider also has a pair of auxiliary ledges on the inner face of the lower wing adjacent to respective front ends of the flanges, each of the auxiliary ledges having a flat top surface disposed below the respective corner ledge for being engageable with the outer or lower leg portions of the respective fastener element row so as to prevent the coupling head portion of the individual fastener element from projecting into an aperture in the upper wing, through which aperture a fastener-element locking pawl is projectable, while the opposed rows of fastener elements are being coupled to close the slide fastener. |
