ABSTRACT OF THE DISCLOSURE A slide fastener having an emergency opening zone at its intermediate point from which the fastener can be forced open in an emergency without pulling a slider along inter- engaged rows of fastener elements. To make this slide fas- tener reusable, a slider escape mechanism is arranged at its top end for causing the slider to ride on only one of the stringers by releasing the other stringer therefrom after the fastener has been forced open. Arranged at the bottom end of the fastener is a connect-disconnect terminal mechanism which may take the form of a box-and-pin separable coupling, such that the fastener stringers can be reconnected to permit nor- mal slider movement after having been completely separated from each other. The present invention thus provides a slide fastener which can be readily forced open in an emergency without manipulating a slider and after having been forced open, the fastener is capable of being restored to an operable state through a simple procedure.
