ABSTRACT:
A joint for connecting tubular beams comprising two caps receiving deformed end portions of the beams therebetween. Each cap has a tapering tubular portion in contact with the end portions, each end portion having first and second outwardly diverging opposed faces and third and fourth inwardly converging opposed faces. The outer perimeter of the end portion is greater than the perimeter of an opening defined on the top and bottom by the two caps and on the sides by adjacent beams, so each end portion is highly resistant to forces tending to pull it from between the caps and must be mechanically deformed before it will be pulled through the opening.
