An improvement in rolling shutters that includes a slat end retainer attached to the ends of individual shutter slats contoured and configured for securing a slat end to the side track which allows the shutters to endure high velocity winds, substantial impact, or attempted forced entry without conventional storm braces. The retainer end includes a pair of contoured inner and outer flanges formed from a unitary body which has a predetermined sized slot that is keyed to fins in each vertical side track to prevent disengagement of the slat from the track.
