<p>A post (58), for example for a fence, a safety barrier or a road sign, has an elongate support member (36) which may be parallel to or angularly offset from the post and a peg (38) extending laterally from the support member. A correspondingly L-shaped slot (18) in a supporting structure (12) such as a building or the ground receives the support member and peg so that withdrawal is prevented when the peg is in the corresponding leg of the slot. A stop (54) is locatable in the slot to prevent withdrawal of the peg from the corresponding leg of the slot. The stop may be carried by the supporting structure or, for example, by the support member. In one embodiment the stop is used to close the slot when the post is removed therefrom.</p> |
