The invention relates to a dashboard cross-member for a motor vehicle, the cross-member comprising a tubular metal structural element assembled to the front pillars of the motor vehicle and at least one air flow duct of plastics material for transporting air to the passenger compartment of the motor vehicle and having at least one segment disposed inside the metal structural element. According to the invention, the metal structural element comprises two assembled-together metal half-shells, and the air flow duct is independent of the two half-shells and has at least a fraction of its segment disposed inside the metal structural element subjected to elastic stress in at least one transverse direction, so that it is pressed at at least two opposite points against the inside face of the structural element under the action of the reaction force against said elastic stress.
