ABSTRACT:
A joint assembly for three tube sections forming the corner of a tube frame, includes a tensioning piece having ends which are hooked into openings provided in mutually facing sides of the first and second tube sections. A tensioning bolt extends through a hole in the tensioning piece and engages in a diagonally disposed threaded hole of the third tube section. The mutually facing sides of the first and second tube sections are exclusively restrained at locations which are immediately adjacent to two opposing walls of the first and second tube sections. The tensioning piece has a U-shaped cross section in a plane which is perpendicular to the common plane in which the first and second tube sections are located. The tensioning piece includes a transverse web extending transversely to the first and second tube sections and two spaced-apart legs which are parallel to the common plane in which the first and second tube sections are located. The U-shape is defined by the transverse web and the two spaced-apart legs. The mutually facing sides of the first and second tube sections have slots immediately adjacent to the opposing walls. The legs of the tensioning piece have boundary portions which engage in these slots. The bolts bears against the transverse web of the tensioning piece.
