Abstract
A downhole tool includes a body having a rounded or cylindrical surface, at least one relieved space in the rounded or cylindrical surface, and a protuberance within the relieved space. The downhole tool also has a generally cylindrical retaining ring that surrounds a portion of the body. One or more crimple detents are formed in the retaining ring, each crimple detent comprising a portion of the retaining ring that has been deformed radially inward into an underlying portion of the relieved space such that the deformed material of the retaining ring contacts and deforms an underlying portion of the protuberance in the relieved space, thereby joining the retaining ring to the body.
