A crush barrier comprises a first frame extending substantially vertically to form the barrier, a second frame extending substantially horizontally adjacent one side of the barrier to form a ground support, the second frame being connected to the first frame, and a plate (3) which lies adjacent the ground on the opposite side of the vertical frame from the second frame. The plate is connected to one of the frames and forms a platform upon which people may stand. The weight of the people standing on the plate prevents the barrier from being pushed over. When not in use the barrier may be collapsed to a compact form which facilitates storage and transportation.
