Protection system i.e. safety barrier, for wall opening e.g. window opening, of building, has rectilinear type bar cooperated between assemblies and forming hollow portion to slidingly receive other rectilinear type bars
The system has parallel rectilinear type bars i.e. tubular/ovoid bars, supported by cross-pieces (3, 4) i.e. hollow tubes, of walls delimiting an opening (7). Two assemblies include the cross-pieces. One of the bars includes an end cooperating with an end of the other bars corresponding to one of the assemblies for assembling the assemblies. The former bar is cooperated between the assemblies and forms a hollow portion to slidingly receive other bars. A curved portion is included in each bar.
