摘要： The invention concerns a radially expandable metal tubular element having on its outer surface a series of spaced apart annular sealing modules. This element is noteworthy in that each sealing module comprises two annular metal abutments between which there are inserted an annular seal and two anti-extrusion rings, the seal being positioned between the two anti-extrusion rings and the two metal abutments being secured against the outer surface of the said tubular element, in that the two anti-extrusion rings are made in elastically and plastically deformable material and are in one or two parts, and in that the two anti-extrusion rings and/or the seal comprise at least two opposite facing bevelled surfaces capable of sliding relative to one another under the effect of axial movement of the said seal so as to cause outward radial displacement of one of the anti-extrusion rings or at least one of the two parts thereof.
