The connecting piece is formed with a substantially flat planar flange to fit about a longitudinally extending slot in the rounded air conditioning duct. Due to the absence of any significant curvature of the duct in the area of the slot, the flat flange requires no rounding to conform to the curvilinear periphery of the air conditioning duct. The connecting piece also has a body of tapering shape which extends from the flange to a rounded connecting pipe.
