ABSTRACT:
A modular barrier includes a plurality of substantially identical barrier sections each section having a base portion surmounted by an upright portion. The upright portion has projections with substantially semi-cylindrical outer surfaces at its ends. Correspondingly shaped recesses are also provided. At a femal end, the base portion includes a nose. The surface of the nose is a surface of rotation of the profile of the base portion. At the male end, the base portion includes a correspondingly shaped cavity. The first and second projections and the nose are provided with bores. When the female end of the barrier section is brought up to a male end of a similar, adjacent barrier section, the projections mate with one another and the nose is received in the cavity of the adjacent barrier section. A hinge pin may then be passed through the bores for allowing one barrier section to be articulated to an adjacent barrier section with the joint between the two portions of adjacent barrier sections presenting an essentially smooth profile irrespective of the angle between the two adjacent barrier sections.
