Claim:
1. A construction system comprising a first elongate member, a second elongate member and a connector member, each of the first and second elongate members comprising an interior engaging portion, the connector member includes a protruding keying portion and first and second mating formations, wherein, when the second elongate member is engaged with the connector member in use, the interior engaging portion slidably receives one of the first and second mating formations therein, and wherein none of the first elongate member, the second elongate member, and the connector member have any moving parts thereon, wherein the connector member has a body that is generally box shaped and comprises an exterior surface having a first face, a second face, and a third face wherein the first face lies entirely within a first plane, the second face lies entirely within a second plane, and the third face lies entirely within a third plane, the first face providing a horizontal surface with the protruding keying portion thereon, the second face and the third face each providing a vertical face, the second face having the first mating formation thereon and the third face having the second mating formation thereon, wherein the second face and the third face are mutually orthogonal and are also orthogonal to the first face, the body comprising a fourth face and a fifth face oriented generally at a right angle to each other, the fourth face having a fourth face protruding keying portion thereon and the fifth face having a fifth face protruding keying portion thereon, the protruding keying portion extending in an “L” shape on the first face and extending in a downward step along a first surface of the first and second mating formations, wherein a first width of the protruding keying portion is less than a second width of the first surface of the first and second mating formations upon which the protruding keying portion extends, the fourth face protruding keying portion extending in a downward step along a second surface of the first mating formation and the fifth face protruding keying portion extending in a downward step along a second surface of the second mating formation, wherein the protruding keying formation of the first face and the fourth and fifth face protruding keying formations have no through-holes therein, the first and second mating formations extending outwardly away from the second and third planes, respectively, a greater distance than a distance that the protruding keying formation extends outwardly away from the first plane, wherein the interior engaging portion of the second elongate member is provided in at least an end portion of an interior of a body which is shaped to slidably engage with one of the first and second mating formations of the connector member wherein the interior engaging portion has a stepped shape as a female part and the mating formation is provided by a stepped formation as a male part, wherein an interior profile of the end portion of the second elongate member is identical to an exterior profile of one of the first and second mating formations, the interior profile of the end portion having second member keying portions that are configured to engage the protruding keying portion that extends on the first surface of the one of the first and second mating formations and the fourth face protruding keying portion that extends on the second surface of the one of the first and second mating formations, respectively, such that a profile of the second member keying portions are identical to the profile of the protruding keying portion on the first face and the fourth face protruding keying portion, respectively.
