The device for closure of building openings has at least one raisable and lowerable curtain, which with its side edges engages in guide rails (11) in the area of the side edges of the building opening. The guide rails have two side legs (17,18) joined to each other by a rib (16), at least one leg being formed as a spring leg (18). The spring leg in the area of its edge remote from the rib has securing devices extending laterally over the rib. The guide rails can be secured in a back-cut accommodation groove (14) in the area of at least one flank.
