A hollow body assembly wherein a circumferential flange is disposed on the outside and/or inside of each of a pair of individual elements to be connected at their connecting surfaces. Each of the flanges has a transverse outer surface which is perpendicular to the longitudinal axis of its respective individual element and an inner surface which is oblique to the transverse direction of the outer surface. A circumferential ring having an inner channel surrounds the flanges when the elements are connected, the ring having side edges for gripping the oblique surfaces of the flanges. The distance between the side edges of the ring when it is in its unstressed condition is less than the distance between the base points of the oblique surfaces of the flanges.
