A shelf system comprises structural rods with hollow ends, coupling elements each consisting of a body and a plurality of spigots for interconnecting the ends of the structural members, and shelf brackets designed to fit the ends of the structural members and to be held thereon by the inserted coupling spigots. On each coupling element one spigot is tubular or rod-like and each other spigot consists of a plurality of flat blades of which the edges define an envelope corresponding to the internal cross sections of the rod ends.

A system for assembling a structural framework, said system comprising a plurality of elongated structural members having hollow ends, and a plurality of coupling members adapted to be fit into said hollow ends for interconnecting said structural members, said coupling members being formed of resilient plastic material, each of said coupling members having a body portion and at least two coupling spigots which project outwardly from said body portion and which are engageable within said hollow ends, at least one of said spigots only comprising flat blades which extend outwardly from said body portion, said blades comprising a plurality of parallel blades extending from said body portion and and a single flat blade projecting outwardly from said body transverse to said parallel blades, said transversely extending blade having first and second ends and interconnecting said plurality of parallel blades, all of said parallel blades being located between said first and said second ends of said transversely extending blade, said blades having edges, said edges together defining an external profile which is discontinuous over the circumference of said spigot, said profile substantially extending over the length of said spigot, said profile generally corresponding in size and shape to a cross-section of one of said ends.
