In a Roman blind, the upper edge of the pleats (9) is connected to a supporting rail (8) which can be raised and lowered in the closing and opening direction. The supporting rail (8) and the pleats (9) have holes (10) at a distance form each lateral boundary of the shaded area formed by the pleats (9). Supporting cords (11) are threaded through the holes (10) and clamped inside a frame (1, 2, 3) surrounding the shaded area to stabilize horizontally the pleats (9). When at least one of the boundaries of the shaded area is inclined to another boundary, a tensioning cord (13) with the same inclination is associated with the inclined boundary. One end of this tensioning cord (13) is connected to the supporting rail (8) and the other end to a roller tensioning device (12) which is fixed inside the frame (1, 2, 3).
