The installation, which includes a tubular enclosure, is provided with a plugging device at each end, each plugging device including a moving assembly that can be displaced perpendicularly to the axis DELTA of the enclosure. The moving assembly includes a plug of the stopper type provided with a seal, a spacer provided with a pull rod a drawer and a plugging body. The moving assembly is slidably mounted in a force take-up member. Via co-operation between sloping ramps carried by the plug and complementary sloping grooves in the drawer, the transverse displacement of the drawer causes the plug to be displaced axially.
