ABSTRACT OF THE DISCLOSURE A slide fastener capable of being forced open in an emergency without manipulating a slider along inter- locking rows of scoops. The slide fastener comprises an emergency opening zone at its intermediate point where the opposed edges of the fastener stringers are incapable of interlocking engagement when the fastener is closed, and a pair of rigid reinforcements fixedly arranged along and on the opposite sides of the zone. Each reinforcement extends beyond both extremities of the zone, so that the fastener will not open accidentally from the zone but will open unfailingly upon application of a finger pressure to the zone in an emergency.
