ABSTRACT:
A louvered air diffuser which mounts to an outlet of an air distribution system of a building and is removed therefrom without tools. The diffuser has two arms which expand resiliently to engage an environmental surface of the air conduit of the distribution system. The arms each have teeth for improving frictional engagement of the environmental surface. The arms and teeth are configured to assure that the arms are urged inwardly, away from frictional engagement of the environmental element, when being installed and removed. Optionally, the teeth have holes with sharp edges, or holes for receiving rubber projections for enhancing grip.
