This patent describes a crankcase breather of the type having an air filter container portion with a tube connector conduit extending outward from an arcuate shaped outboard wall of the container portion and which is adapted to be secured in and against the upright wall of the outer housing shell of an air cleaner. The tube connector conduit projects out through the upright wall of the outer housing shell. The improvement described here is wherein the crankcase breather includes a raised boss retainer portion extending outward from the outboard wall and encircling the tube connector conduit. A U-shaped groove is located in the lower portion of the raised boss retainer portion. The upright wall of outer housing shell has an aperture therein of a configuration conforming to the base of the U-shaped groove and the adjacent upper portion of the raised boss retainer portion whereby the groove can receive a portion of the material of the upright wall defining the aperture. The remainder of the raised boss retainer portion can be snapped into locking engagement with the remaining edge portions of the upright wall defining the aperture.
