Crossbar (2) for heald-carrying frames of weaving looms comprising a main element of the crossbar made, at least in part, of a light metallic material, such as aluminium, magnesium or alloys thereof; and a heald-carrying element (1) made of a high-resistance material, such as steel. The heald-carrying element is steadily fastened to the main element of the crossbar by means of a lock joint, through plastic strain between a longitudinal rib (4) projecting from the main element of the crossbar and a corresponding groove (3) formed in the heald-carrying element (1).
