A clothes dryer vent hood is fabricated of plastic by an injection molding process, and is provided with an integral rearwardly open annular portion for receiving a tubular member or pipe, which pipe is made of metal, and has several radially inwardly projecting tabs formed at the open end which is to be assembled with the annular portion of the vent hood. This annular portion is molded to define L-shaped grooves for receiving the tabs, and each groove has an abutment defined therein such that the hood can be assembled with the tubular member by axially joining these parts to move the tabs past these abutments in the grooves, followed by a twisting motion of the parts to further lock them together.
