Sealing joint for the connection of a tubular branch-off connector to a cast iron sewage pipe (drain) provided with a cement-based covering, of variable thickness. In the annular space between the connection or branch-off connector T and the edge of the tee-connection opening O on the pipe C there is interposed a sealing gasket G with external lips 2 and 3 covering the edge of the said opening O and with an internal flange 6 and single internal lip 7 which radially compress the body of the gasket G against the edge of the tee-connection opening O. Moreover, the branch-off connector T which traverses the sealing gasket G comprises an end protuberance 18 and a collar 21 for locking with respect to the gasket G. Locked and sealed connection, without bolts, capable of angular branch-off movement. <IMAGE>
