Title: Slide fastener

Abstract: An open end type of slide fastener has an end stop comprising a pair of lugs formed from a plastic material and secured to the longitudinal edges of respective stringer tapes, each lug having an oblique inner edge extending divergently with respect to the longitudinal axis of the fastener such that the lugs define therebetween a substantially V-shaped opening complementary in shape with the diamond of a slider. One of the pair of lugs has at least one projection continuous to the oblique inner edge and the other lug has a recess receiving the projection. The projection extends transversely beyond the central longitudinal axis of rows of interengaged fastener elements and is disposed for abutting engagement with the slider diamond. When the diamond moves past the projection and spreads the lugs apart, the uppermost opposed coupling elements become disengaged to allow smooth movement of the diamond therebetween.
