Joint seal for concrete tubing rings includes sealing strips positioned on opposite front surfaces of adjoining segments of the tubing rings and joined together by an adhesive or a welded attachment. Both sealing strips (2,3a) of the adjoining segments embrace with their flanges (4,5) corresponding corners of front surfaces of the segments. - The sealing strips (2,2a) are positioned flush with each other on outer edges of the segments (1) and are embedded in the concrete. The adhesive joint is provided with a sealing band (16) which projects over outer surfaces of both segments and is attached to flanges (4) of the sealing strips (2,2a). The sealing strips are symmetrical. They have ribs (7 to 9) of the same thickness as their flanges by which they are embedded in the concrete.
