Abstract
A pipe to be placed within a well for producing a fluid of interest includes an outer face onto which is crimped a tubular metal element. The inner face of the tubular element exhibits an annular groove in which a metal anchoring ring or a pair of juxtaposed anchoring rings is engaged. Each anchoring ring consists of a ring split transversely at least partially, is provided on its inner face with projecting anchoring members, and exhibits, in cross-section, a base equipped with the projecting members and at least one flank forming an acute angle with the base. The annular groove exhibits a profile that is substantially complementary to that of the ring(s). The depth of the groove is less than the thickness of the ring or of the rings. The projecting members are at least partially embedded into the pipe after crimping of the metal element onto the pipe.
