ABSTRACT:
The invention relates to scaffolding in which the uprights have sockets projecting outwardly at spaced positions along their length, the horizontal cross members of the scaffolding having spigots to engage in the sockets, a captive wedge being provided to cause the spigots to be clamped against the socket or upright. Such scaffolding in accordance with the invention is arranged so that in use the spigot is inserted into a socket and the wedge acts between the outside surface of the socket on the surface of the cross member tightly to draw the spigot against the corresponding inside surface of the socket. The "lower" narrower end of the wedge is formed or provided with a projection which, when the wedge is moved upwardly relative to the cross member it wedges against the surface of the cross member to hold the wedge in the withdrawn "uppermost" position so that the spigot can readily be removed from the socket.
