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.
