Air outlet as fitting piece for motor vehicles

The outlet has a hollow housing (1) attached to an air flow channel, and lockable actuating knobs (2, 7) for commonly adjusting lamellas (5). The actuating knobs are movably held in a sleeve-shaped hub (8) of a holder and releasably lockable in the hub. A brake lining (4.2) indirectly couples the actuating knobs with a lever (4.1), where the lever is fitted at a wall or an extension part (1'') of the housing when the brake lining resides in a spot ventilation position and is positioned at a distance from the wall when the brake lining resides in a diffusion-ventilation position.
