Abstract: A securing device is provided comprised of a reactive fiber component and at least one of a terminating fiber component and an initiating fiber component. The reactive fiber component includes at least one of the following: an undrawn polymer fiber and a substantially undrawn polymer fiber, wherein the first reactive fiber component is operative to stretch responsive to a load. The terminating fiber component is in a compressed state and is operative to elongate to a length at which the terminating fiber component is operative to prevent further stretching of the first reactive fiber component responsive to the load. The initiating fiber component is operative to break responsive to a predetermined force and permit the first reactive fiber component to stretch responsive to the load.
