<p>An air filter comprises a female portion of a connecting duct having two parallel longitudinal and diametrically opposed openings to house flanges that project to the outside of the wall of an intake duct; and removable fastener for securing the filter to the intake duct. An air filter comprises a duct for coupling to an intake duct. A female portion of the connecting duct is intended to cover a male portion of the intake duct. The female portion has two parallel longitudinal openings intended to house within them flanges which project to the outside of the wall of the intake duct with which the coupling duct is intended to engage. The two openings are preferably diametrically opposed. The female portion includes an end piece in the form of a frustoconical chamfer (4) so that the female portion is of greater size in cross-section than the remainder of the coupling duct. A removable fastener is provided for securing the filter to the intake duct. Independent claims are also included for: (a) an intake duct produced by thermoforming, made of non-woven material, especially polyester, and including two flanges in parallel to the longitudinal axis of the duct, projecting from this outer surface of the duct and diametrically opposed, wherein the thermoformed intake duct includes, at its free end, an annular bulge (8) intended to butt against a chamfer of an air filter; and (b) an assembly consisting of a filter and a duct.</p> |
