A closure device comprises a zipper, a first elongate coupling element, and a second elongate coupling element lockable along its length to the first elongate coupling element. The zipper is slidably connected to the first elongate coupling element for locking the elongate coupling elements to one another by a closure stroke of the zipper and for alternately unlocking the elongate coupling elements from one another by an opening stroke of the zipper. A first snap lock fastener is connected to the first elongate coupling element at one end thereof, while a second snap lock fastener is connected to the second elongate coupling element at a corresponding end thereof. The snap lock fasteners are releasably connected to one another in snap lock fashion to align the one end of the first elongate coupling element with the corresponding end of the second elongate coupling element, thereby facilitating the closure stroke of the zipper.
