Abstract
A joint is provided for connecting an end of a tube of composite material which is subject to relatively large axial stress to an annular metallic ferrule, and includes a composite tube composed of high strength fibers agglomerated by a polymerized synthetic resin having a wall and an annular metallic ferrule formed as a band. The ferrule has in cross-section the shape of a segment of a circle including a curved portion and a flat portion, the curved portion of the ferrule facing the composite tube. The ferrule is embedded in a receiving surface of the wall of the tube, and the flat portion of the ferrule is flush with adjacent regions of the receiving surface of the tube. An end member is included having an extending portion which engages the ferrule, and a complementary connecting device is disposed between the flat portion of the ferrule and the extending portion of the end member, for connecting the tube to the end member. The band and the complementary connecting arrangement together constitute an anchoring element for anchoring the tube of composite material to the end member.
