3An accident-prevention device for buildings, particularly for assembling prefabricated components made of concrete, which comprises at least one pole and elements for detachably connecting the base of the pole to the surface of a building. The pole has, proximate to its tip, guiding pulleys for a cable element which forms a safety parapet. The guiding means are adapted to divert, in a direction which is substantially parallel to the axis of the pole, at least part of the stresses transmitted from the cable element to the pole, and the pole is provided with shock-absorbing elements for cushioning the stresses transmitted from the cable element to the pole in a direction which is substantially parallel to the axis of the pole.
