A lead bar for a retractable awning, of the type constituted from a hollow profile obtained by extrusion of a light metal alloy, comprising:

• a longitudinal canvas-securing groove for fixing the front edge of an awning canvas and a longitudinal arm-securing groove for securing the front end of at least one arm, said profile having a cross-section with a surrounding wall that defines:
• a wide region, in which said surrounding wall comprises upper, lower, front and rear portions located away from a central geometric axis;
• and
• an elongated region, in which said surrounding wall comprises elongated front and rear sections facing each other and located close to a geometric mid-plane between them, said elongated region projecting downwards from said lower potion of the wide region next to a front edge thereof;
• said longitudinal canvas-securing groove and said longitudinal arm-securing groove are arranged respectively on said upper portion and on the lower portion of the wide region in substantially directly opposite positions in relation to said central axis, said profile comprising a partition wall that separates the wide region from the elongated region, said partition wall connecting an interior part of said longitudinal arm-securing groove and an area of the surrounding wall where said front portion of the wide region and said elongated front section of the elongated region meet together.
