ABSTRACT:
A first extension member has a head coupled to a first zipper head and a tail having a male connector and an elongated generally flat intermediate portion between the head and the male connector. A second extension member has a head coupled to a second zipper head and a body with a female connector that receives and locks the male connector and receives and permits free sliding movement of the elongated flat intermediate portion.
The female connector prevents removal of the male connector therefrom to prevent opening the zipper beyond a predetermined position based on the length of the elongated intermediate portion. Because the male connector is positioned generally at the end of the tail and the elongated intermediate portion is generally flat, the tail may slide freely within the female connector between the head and the male connector so that the zipper is therefore not locked in any fixed position.
