A concertina-type protective arrangement for an outer wall of a building serves for covering the space in front of the facade (1) of a building with a view to protecting the openings of the building, and is aligned parallel with respect to the outer wall. A covering awning is supported by elements incorporating a supporting pillar (3) and a cross-member (4), each element having rollers which run on two guide rails arranged lengthwise along the outer wall (1). <IMAGE>
