Abstract: A support assembly for e.g. a scaffold support platform, comprises two horizontally spaced elongate elements 10 mounted between two longitudinally spaced supports 12 and 14 by means of respective hook connectors 16 and 18. The elements 10, connectors 16-18 and supports 12-14 are so dimensioned and arranged with respect to one another that upwardly directed disconnection of the connectors from their supports is prevented unless the element 10 is first deliberately displaced in a direction parallel to its longitudinal axis. Upon such displacement, the element 10 may be tilted upon one support to permit upwardly directed disconnection from the other support.

Abstract: A releasably engageable builders scaffolding assembly comprises an upright member, cross members and brace members wherein a cross member and a brace member are connected to the upright member by means of a wedge securing both said members to a socket on the upright member. A cross member is connected to the upright member by means of a channel shaped connector straddling a socket and affording a space therebetween for the reception of a grooved spigot extending from a brace member which spigot is retainable by the wedge passing through the cross member connector and a socket.
