Abstract: A connector is provided for hingedly connecting two substantially identical, elongate profile members together. These profile members define the rigid peripheries or frames of freestanding display panels or screens. Each connector comprises two link members, each having an elongate web carrying two spaced pivot pins, and two connecting parts. Each connecting part is either constituted by, or has the same profile, as a profile member. The connector enables the two profile members to be pivoted between a facing position and a side by side position. In one of these positions the two link members extend parallel to one another, while in the other of these positions, the two link members cross relative to one another.
