A device for securing the shafts of buildings, for example light shafts, against forcible intrusion or passage. The device includes at least one hollow blocking bar which spans the shaft transversely and the two ends of which are held in respective anchor members attached to the wall of the shaft with covered bolts and which contains a hollow security rod of substantially the same length. The blocking bar has the form of a polygonal prism the ends of which are received in form-fitting manner in respective recesses of associated respective attachment bases in such a way that they lie in opposing alignment to the mounting bolts of the base and are secured against pull-out by a latch member lock. The device is especially distinguished in that it offers a maximum of security against forcible intrusion while requiring a very small amount of technical and installation effort, by, firstly, giving access to the mounting bolts only after all of the blocking bars have been removed and, secondly, in that the shaping of the blocking bars contributes positively to maintaining the functional security of the components taking part in the anti-intrusion function as long as possible.
An elevator safety barricade adapted to prevent inadvertent entry into an elevator shaft comprised of a pair of opposed pockets in the opposite side plates of an elevator opening and a pair of overlapping restraining bars with one end of each restraining bar inserted into each of the openings. The pair of restraining bars are held in place in rigid relationship with each other to provide a rigid barricade.

Connectors for attaching a false front panel over an opening in an object comprise a post piece that is configured to attach to the object and a clip piece that comprises a base that is configured to attach to a rear face of the false front panel and at least one snap clip projecting from the base that is configured to receive the post. The post piece of these false front connectors includes a post that has a non-circular cross-section (e.g., a diamond shape), and the interior of the snap clip may also have a non-circular cross-section that is matched to the cross-section of the post.
