ABSTRACT OF THE DISCLOSURE An open end slide fastener comprises a pair of string- er tapes each carrying along one longitudinal edge a row of coupling elements and a pair of end stop lugs, each of the coupling elements including a pair of spaced legs and a coupling head extending therebetween. The coupling head has a pair of lateral projections extending longitudinally of the row of coupling elements beyond the width of the legs. The lateral projections of the coupling heads of the opposed endmost coupling elements located next to the top end stop lugs are cut off to permit the endmost coupling elements to be disengaged from each other when the fastener is closed. The legs of one endmost coupling element are partly cut off to define a slot extending transveresely of the rows of coupling elements. The invention thus permits the endmost coupling elements to move unobstructedly toward and away from each other, to improve the smoothness of the movement of the slider within the region of the end stop lugs.
