Abstract: To connect a connection element (12) to one end (10A, 10B) of the strip (10) from which the swaging ring is made, the connection element is placed against said end in such a manner that at least one anchor edge (14) of the connection element (12) is in register with said end, and pressure is exerted on the connection element (12) so as to displace the material of said end (10A, 10B) of the strip that lies beneath the connection element (12) while forming a fixing member (15) in said end that is suitable for co-operating with said anchor edge so as to hold together the connection element and said end of the strip.

Abstract: A crimping ring comprises a rolled-up piece of metal strip (10). A first connection means formed at the first end (12) comprises a first setback overlap surface (16) together with at least one female member (18) recessed from said first surface. A second connection means formed at the second end (14) comprises a second setback overlap surface (20) together with a male member (22) formed to project from said second surface. On connection, the male member (22) is engaged in the female member (18) and is fixed thereto, while the overlap surfaces (16, 20) are disposed one against the other so as to define a connection zone of thickness that is substantially equal to the thickness of the main portion of the strip.
