Abstract
A joint between two metal tubes may be formed by creating a cutout on each of the tubes, each cutout having a pair of channels sized according to a wall thickness of a tube to be received, and then pressing the tubes together. Teeth are formed in the channels to engage the wall of the opposite tube when the tubes are pressed together to prevent the joint from separating once created. Optionally a mechanical fastener may be used to further strengthen the joint structure.
