A road safety barrier having a plurality of ropes supported by posts rigidly mounted on or in the ground is described. Each rope is held in tension against the posts and supported in a notch or groove in a side of the posts. The ropes are released from a post and the post is not pulled from the ground when a vertical force is exerted on the rope.
