Abstract
A sealing device is provided suitable for making at least partially fluid-tight a connection between a first pipe and a smaller second pipe, a part of the second pipe being able to be engaged in the first pipe while leaving an inter-pipes space between the two pipes in the radial direction. The sealing device is mounted on a supporting pipe and is adapted to spread out in the inter-pipes space from a guard position to a sealing position. It comprises at least one sealing set including substantially rigid movable sealing members which extend each along a predetermined angular sector in a circumferential direction and are individually guided in displacement between the guard position and the sealing position.
