A demountable structure, for example for forming scaffolding, shelf assemblies or frame assemblies comprises a pair of co-axial spaced connection and support members with a connection element or bracket interposed between the ends of the members. The engaging surfaces of the support members and brackets form frustum cone surfaces and are drawn together and stiffened by a threaded stem passing therethrough.
