ABSTRACT:
A link for use in a flexible support for a light fitting comprises a first section which has a part spherical outer surface and a second section which is connected to the first section and has a part spherical internal surface and a slot opening into said second section. Two similar links can be connected to make part of a flexible support by introducing the first section of a first link into the second section of a second link. The part spherical outer surface of the first section of the first link frictionally engages the part spherical internal surface of the second section of the second link so that the links can be placed in a desired position with respect to one another within limits imposed by the geometry of the slot.
