A perimeter security barrier (1) for restraining a vehicle impacting the barrier from a direction substantially perpendicular thereto is described. The barrier comprises a pair of spaced apart end posts (3, 5) rigidly fixed in the ground and intermediate posts (11a, 11c) disposed between the end posts are also fixed in the ground. At least one pair of wire ropes (15c, 15d) is supported between the end posts and optionally woven around the intermediate posts, the ropes being secured at each end to respective end posts. Energy absorption means (21) is provided at each end for absorbing energy transmitted by the ropes from the impacting vehicle. |
