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.
