Abstract: Arrangement of slat screens for solar protection of the type having a number of slats (24;44) supported by girders (5) or the like, which slats are placed apart from each other and together form a solar screen. The girders (5) have slat holders (16) with projections (21) with surfaces which face away from each other. These surfaces slope in such a way relative to each other that they form together an entry portion (22) which on the inside is terminated by a groove (23) in each projection. The slats (24) are provided with a fixture (28,29) which has two opposing flanges (28) with outer hook-shaped projections (29) facing each other. The distance between the flanges is so chosen that the hook-shaped projections can be guided onto the widened out entry portion (22) so that during the bending of the flanges they are made to pass the widest part of the entry portion which is wider than the distance between the hook-shaped projections.
