Composite sleeve-shaped sealing means for the sealing of the annular space between two partly overlapping bodies (2,3) having walls of a different diameter, such as two pipes (2,3) or a line and a wall passage for it, in which the sealing means comprises a cylindrical casing composed of two or more similar longitudinal members (4) and an end flange (6) formed at one end of the casing (5), which are intended to be accommodated in the annular space and to be placed against the end edge of the widest pipe (2), respectively, the casing (5) at its outer surface being provided with a number of first circumferential ribs (7) spaced apart in axial direction, and at its inner surface being provided with a number of second circumferential ribs (8) spaced apart in axial direction, a final second circumferential rib (8a) being formed at said one end of the casing (5) at the inner circumference of the end flange (6), which rib substantially retains its shape. <IMAGE> |
