ABSTRACT:
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 interengaged rows of fastener elements. To make this slide fastener 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 stringer can be reconnected to permit normal slider movement after having been completely separated from each other.
