Abstract
A security post assembly consisting of a base tube to be sunk into the ground or other base and a post which fits into the mouth of the tube is lockable by a mortise lock mounted inside the post above ground level. The bolt of the lock protrudes outside the post and into a receiver structure carried on the underside of a cover plate which is hinged to the base tube and which can be swivelled to stand up beside the post. The receiver structure comprises a U-shape flange which fits inside a U-shape guard plate attached to the post.
