ABSTRACT:
A coupling assembly for joining together the ends to a pair of tubes, particularly suitable for use with plastics material, includes a pair of flange bushings, a sealing arrangement effecting a centering function and two semicircular shells having a U-shaped inner cross-sectional profile, each of the shells being provided with a resilient pawl which joins the shells together circumferentially about the coupling assembly. The sealing arrangement includes a centering ring and an inner sealing ring with the outer diameter of the centering ring performing in cooperation with the inner contour of the shells a centering function for the sealing arrangement. This centering function prevents displacement of the sealing arrangement during assembly and operation and permits the utilization of different types of seals and of smooth end faces of the flange bushings.
