The present invention relates to a crash barrier which is adapted to be arranged in the middle of a dual carriageway and which is composed of a plurality of elongate barrier elements (1), preferably made of concrete, which are arranged successively with the short sides of the respective barrier elements neighbouring each other. Neighbouring barrier elements (1, 1') are interconnected by means of articulated connections (5, 6, 5', 6', 8), which prevent lateral displacement of the interconnected short sides relative to each other, but permit force-absorbing deformation of the crash barrier by pivoting of the barrier elements relative to each other in case a vehicle collides with the crash barrier. Each barrier element has at least two projecting connecting elements (5, 6) from each short side, which are connected with corresponding connecting elements (5', 6') of a neighbouring barrier element (1') by means of a rod (8) which is passed through holes (7) in each connecting element. A sleeve (9) cast into the barrier element (1) permits limited displacement of the connecting elements (5, 6) between two end positions.
L'invention concerne une glissière de sécurité destinée à être placée au milieu d'une route à double voie et constituée de plusieurs rails (1), de préférence en béton, disposés successivement, les petits côtés des rails respectifs étant adjacents. Les rails adjacents (1, 1') sont reliés à l'aide d'éléments articulés (5, 6, 5', 6', 8), ce qui empêche le déplacement latéral des petits côtés reliés les uns par rapport aux autres mais permet la déformation absorbante de forces de la glissière par pivotement des rails les uns par rapport aux autres si un véhicule entre en collision avec la glissière. Chaque rail a au moins deux éléments de connexion (5, 6) faisant saillie sur chaque petit côté et assemblés par les éléments de connexion correspondants (5', 6') du rail adjacent (1') à l'aide d'une barre (8) que l'on introduit dans des trous (7) pratiqués dans chaque élément de connexion. Un manchon (9) coulé dans le rail (1) permet un déplacement limité des éléments de connexion (5, 6) entre deux positions terminales.
