Abstract
A radially expandable tubular metallic element includes on its external face at least a series of annular sealing lips made of elastically deformable material. These lips are spaced in pairs. The transversal cross section of each lip has an end face and two lateral walls, wherein the lips are made of a non-metallic material and are inclined in the same direction, relative to said external face, that is, each of the lateral walls of each lip forms a non-zero angle (α; β) relative to a radial plane of said element.
