A barrier comprises posts, an impact-absorbing rail, and a pretensioned steel cable extending in the longitudinal direction of the barrier. The steel cable is arranged in an upwardly open undercut groove in cable holders on the posts. The impact-absorbing rail has the form of a downwardly open sectional rail, which covers the steel cable and the major part of the cable holders. An elongate fibre-optic light guide is fixed to a downwardly directed surface of this impact-absorbing rail. |
