A post for supporting a crash barrier rail is disclosed. The post is a one piece plastics moulding comprising a leg from the upper end of which projects a shoulder having an outer face which is shaped to conform to the inner face of the rail. The post has a flat upper face for driving the post into the ground. A nut is moulded into the post and a passage extends between the outer face of the shoulder and the nut for receiving a bolt by means of which the rail is fixed on the post. A transverse passage may be moulded into the shoulder to provide a ligament joining the lower part of the outerface of the shoulder to the leg. This ligament will yield preferentially when the rail undergoes impact, providing increased elasticity to the barrier. The leg may be provided with a peripheral recess at which the leg will shear preferentially. The post may be moulded of recycled plastics.
