The invention relates to a protective roller blind for openings in walls. It will find its application in particular in the building trade when using blinds protecting doors, windows or the like. It is characterised by the fact that it comprises self-locking means 10 placed in the rolling-up zone 9, linking the drum 6 and the curtain 3 of the blind, in order to prevent the upper part 11 of the curtain 6 oscillating in the rolling-up zone 9 during non-authorised raising of the curtain 3, the blind 1 being in the closed position with the curtain 3 lowered. <IMAGE>
