The sealing device (5; 15) is suitable for making at least partially fluid-tight a connection between a first pipe (1) and a smaller second pipe (2), a part of the second pipe (2) being able to be engaged in the first pipe (1) while leaving an inter-pipes space (D1) between the two pipes (1, 2) in the radial direction. The sealing device is mounted on a supporting pipe (1, 2) and is adapted to spread out in the inter-pipes space (D1) from a guard position to a sealing position. It comprises at least one sealing set (10, 11; 20, 21; 10') including substantially rigid movable sealing members (12; 22; 12') which extend each along a predetermined angular sector in a circumferential direction and are individually guided in displacement between said guard position and said sealing position. |
