ABSTRACT:
A pair of top stop members of a synthetic resin are integrally united with several topmost scoops of respective continuous coupling elements of a slide fastener so as to cover at least the head portions of the scoops. In order to prevent deformation of the stop members as a result of forced contact with each other at the end of the fastener closing movement of a slider one of the stop members is made shorter than the other stop member. Thus, when the slider is moved to a topmost position on the rows of coupling elements, the scoop positioned immediately under the lower end of the shorter stop member abuts against the longer stop member, while the stop members themselves are held out of contact with each other.
