Abstract

The invention relates to a pipe connection of the air duct port with an insulation lagging wall in a ventilation or air-conditioning system, where at least one component (port (1) or lagging (2)) is made of flexible plastic, and where the port (1) along the section of the external sleeve (1.1) extending outside of the wall (2) has a diameter (dz) equal to the internal diameter of the air duct (4), and at the other end the flange (1.2), which is press-fitted with the circumferential surface and is abutted against the shoulder (2.1) of the wall opening (2), characterized in that the port (1) has, on the side surface of the flange (1.2), at least one wave-shaped bulge (1.3) with the largest height enabling press-fitting of the port into the shoulder of the opening within the range of elastic deflection of the material, and axially behind the flange (1.2) there is a sleeve section (1.4) which is lightly press-fitted in the internal opening of the shoulder (2.1), moreover in the corner of the front face of the flange (1.2) there is a groove (1.5) with a semi-circular profile, in which the O-type sealing ring (3) is embedded.
