Connection system

A connection system comprising first and second members and a connecting element for interconnecting the first and second members, said first and second members each having a face with a connecting aperture therein opening into an internal space within the member, said connecting element comprising a bridge portion and a pair of spigot portions one at each end of the bridge portion and extending transversely of the bridge portion along a spigot axis;

• wherein the internal space of each member includes means for restraining the spigot portion against tilting movement about the spigot axis, said restraining means including an engaging portion for snugly receiving the respective spigot portion and wherein said engaging portion is bounded by a peripheral structure defined within the member and adapted to cooperate with the spigot portion to restrain the spigot portion against tilting movement within the engaging portion about the spigot axis;
• said first and second members being interconnected by inserting the spigot portions of the connecting element into the openings in said members and displacing each spigot portion with respect to the respective member along the spigot axis such that the spigot portion is snugly received and retained in said engaging portion of the internal space of the member.
