The invention relates to a stiffener for a fuselage, including a hollow section which can be trapezoidal, which has a base (11) attached to the fuselage or to the floor, relatively high vertical sides (13, 14), and a top side (12) contributing to the rigidity of the stiffener (10) and to the cohesion thereof. A direct assembly to the fuselage (5, 9) is possible. The base consists of two edges (15, 16) arranged one above the other or one in front of the other. Said rigid stiffener, despite the non-continuous cross-section thereof, can be manufactured by simple folding operations of an initially planar metal sheet.
