Each member includes a groove containing a U-shaped slider and a U-shaped resilient seal, the seal being between the slider and the bottom of the groove to urge the slider outwardly. Each seal has a projection at the ends of the legs on which the ends of the slider legs rest. The seal on the stop member has a connecting link.
