Abstract
The cross-piece portion of a tubular T-joint has a cross-section of constant inside diameter from one end of the cross-piece to the other and increasing outside diameter from one end towards it center, then decreasing from its center towards it opposite end to define a double tapered tube wall for the cross-piece of maximum thickness at its center. A stem portion for the T-joint is in the form of a hollow tube extending normally away from the center portion of the cross-piece to terminate in a free end. The cross-section of the stem has a constant inside diameter from its free end to its point of interception with the cross-piece and an outside diameter increasing from its free end to its point-of-interception with the cross-piece so that the maximum thickness of the T-joint is at the interception between the cross-piece and the stem and yet the inside diameters are all uniform so that other tubes can be readily telescoped through the cross-piece.
