    a closed end;

    a longilinear main branch extending in a transverse direction and including one end which forms the closed end and an other end which forms the connection end, one face of the main branch being pierced with a plurality of orifices comprising a first orifice provided at said closed end, and a second orifice located upstream of said first orifice in a direction of air flow from the connection end toward the closed end;

    a single branch extending from the main branch, wherein the single branch is a secondary branch extending from a shared portion of the main branch, the secondary branch and the main branch being positioned on opposite sides of a common wall, with one end of the secondary branch connected to the main branch and a free other end that is closed, the secondary branch including at least one other orifice on a face located on a same side of the duct as the plurality of orifices of the main branch, the at least one other orifice located on the secondary branch is positioned above the first orifice and the second orifice of the main branch in a vertical direction; and

    an attachment bracket positioned extending outward from the closed end, the opening of the connection end and the attachment bracket forming opposite ends of the air distribution duct in a longitudinal direction,wherein the secondary branch is located between said connection end and said second orifice and airflow traveling through the air distribution duct from the heating and/or air conditioning device is distributed to the first and second orifice of the main branch and the other orifice of the secondary branch, andwherein the orifices pierced in the main and secondary branches open out on a same plane and the attachment bracket and the connection end extend in front of the plane in the longitudinal direction.
