Abstract
A joining element for square U-Shaped channelled structural members that have formed longitudinal ribs and an open slot. The joining element comprises a central body having one or more cruciform shaped protrusions. Each protrusion has a plurality of landing surfaces that engage with the channelled structural member so that when a protrusion is inserted into the end of the channelled structural member the landing surfaces of the protrusions positioned inside the arms of the crucifix protrusion, engage the free edges of the longitudinal ribs making a snug fit. The plurality of landing surfaces allows the channelled structural members to be independently rotated so that the open slot formed by the longitudinal ribs is oriented in the desired direction.
