Abstract: 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 side of the respective barrier elements neighboring each other. Neighboring 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 neighboring barrier element (1′) by means of a rod (8) which is passed through holes (7) in each connecting element.
