<p>A screening device for screening an aperture, in particular to be mounted on a building element surrounding an aperture (6) in a building, said screening device comprising a screening member having one end (4) adapted to be secured on an element surrounding the aperture (6) and an end (5) adapted to be moved between a first position, in which the screening member (2) is rolled up, collapsed or folded, and a second position, in which the screening member extends over substantially the entire aperture (6). The screening device comprises two cords (7, 8) for parallel guidance of the free end (5) of the screening member. The cords are at one end connected by tension springs (9) with a mounting member (10) for tightening the cord. A marking (12) is associated with each tension spring (9), and a marking (11) is associated with the screening device at a predetermined position, such that the cord has a tension suitable for the parallel guidance, when each of the markings (12) associated with the tension springs (9) substantially matches the marking (11) at the predetermined position.</p> |
