ABSTRACT OF THE DISCLOSURE A slide fastener slider includes a pair of parallel spaced wings each having a generally W-shaped front edge extending between a pair of flanges extending along the opposite lateral edges of the wing across a neck interconnecting the wings to define therebetween a substantially Y-shaped guide channel. The front edge has a pair of outer portions respectively disposed adjacent to the flanges and projecting forwardly beyond a pair of planes extending respectively between a front end of the neck and respective front ends of the flanges. Each of the wings has a pair of sloped interior guide surfaces extending respectively along the outer portions of the front edge and facing forwardly of a slider body of the slider. When a pair of rows of coupling elements is introduced into the guide channel in a tilted condition, the tilted individual coupling elements are substantially brought back into their normal position as their leg portions slide along the sloped guide surfaces on one of the wings prior to arrival of their coupling heads at the front edge of the other wing. The slider is capable of sliding smoothly along the coupling elements even when the coupling elements are tilted with respect to the general plane of stringer tapes of the respective fastener.
