Abstract
The radially deformable pipe of the invention is made up of at least two sections releaseably coupled end to end. The end of one of the sections has, over a predetermined axial length, an internal perimeter substantially equal to the external perimeter of the end of the other section, so as to form a male end adapted to be inserted in a female end. The extreme margin of the male end includes a locking bead adapted to fit in sealed manner in an internal groove of the female end behind a locking bead including the edge of this groove (9). The extreme margin of the female end is fitted into an external groove of the male end spaced from the locking bead by the said axial length.
