<p>An apparatus for connecting section bars (2) for the fabrication of planar frames (3) in particular of frames for windows and doors, in which the section bars (2) are provided with a cavity (4) with open contour, delimited by a base wall (5) intermediate to two lateral walls (6) transverse thereto - comprises a rigid connecting body (7), of angular shape, able to be housed in the cavity (4) of the section bars (2) astride their junction area, located on a vertex of the frame (3); and securing means (8,11) for securing the section bars (2) of the frame to the connecting body (7). The connecting body (7) and the securing means (8) are shaped to secure the section bars (2), at least in the plane (xy) of the frame, securing mechanically to their single lateral wall (6) of the respective cavity (4). <IMAGE></p> |
