    Abstract: A connector is used to join sheets of fibrous insulation into a duct. The connector includes a base plate to which a plurality of guide flanges and penetrating flanges are connected. The penetrating flanges are spaced from and parallel to the guide flanges, and both the penetrating and guide flanges project from the base plate. In use, the guide flanges bear against the outer surface of the insulating sheet while the knife-like edges of the penetrating flanges penetrate and mesh with the longitudinal fibers of the insulation.
