A pair of bottom end stops are applied to the respective inner longitudinal edges of the inner and outer tapes at their trailing ends. A slider is threaded onto each pair of stringers to couple and uncouple the same. The slider has a lower wing and an upper wing provided with means for holding the trailing end portion of the element row carried on the inner tape.
