Abstract
A duct is shaped and sized for connectability to a vent (or vent adaptor). The duct has an end portion with a flared section separated from a tapered flap section by a lip. The flaps are foldable inwardly at the lip upon engagement with the vent, and airflow through the duct presses the folded flaps against the vent for additional securement of the connection between same. Additional securement and stability may be provided by an adhesive retaining a tapered flap section to a flared section following inward folding of the tapered flap section.
