ABSTRACT:
A slider for heavy duty slide fasteners equipped with a pair of pull tabs pivotally connected to the upper and lower wings of the slider. At least one of the pull tabs has a locking means situated within the width of the pull tab and movable into a position close to and forward of the slider entrance end to engage a top end stop inserted within the Y-shaped guide channel in the slider. The two pull tabs are further provided with an engaging member and a socket member, respectively, both members being snap fittable with each other when the pull tabs are rotated into the locking disposition thereby preventing the locking means from being accidentally forced out of engagement with the top end stop under severe stresses exerted on and around the slider.
