Slide fastener

An open end slide fastener comprising a pair of stringer tapes each carrying a row of coupling elements along one longitudinal edge, each of said coupling elements including a pair of spaced legs supported on one of said tapes and a coupling head extending between said legs, said coupling head having a pair of lateral projections extending longitudinally of the row of coupling elements beyond the width of the legs so that the rows of coupling elements can be interlocked together by interengagement of said lateral projections of the opposed coupling heads, a slider having a diamond and adapted to open and close the fastener, and a top end stop including a pair of lugs secured to the longitudinal edges of the respective stringer tapes, said lugs having oblique opposed edges extending divergently with respect to the longitudinal axis of the fastener and jointly defining therebetween a substantially V-shaped opening complementary in shape with the diamond of the slider, said interengaged lateral projections of the coupling heads of the opposed endmost coupling elements located next to said top end stop lugs being cut off to permit said endmost coupling elements to be desengaged from each other when the slide fastener is closed.
