The dust tube is formed from a generally rectilinear blank of flexible plastic material having a series of holes punched along the upper edge thereof spaced to match the retainer tabs. The blank is curled into cylindrical tube that is subsequently inserted into the cover plate and turned until the retainer tabs enter corresponding holes in the upper end of the tube so that the tube is fixed to the cover plate.
