A cross groove type homokinetic joint is disclosed which requires no boot adaptor, and is thus less expensive than a conventional joint. The joint is provided with an arrangement for preventing the balls from dropping out1 while enabling a shaft (5), secured to an inner ring (1) of the joint, to assume a large working angle ( theta ) relative to an outer ring (4) of the joint. The inner ring (1) has grooves in its outer surface, balls (3) received one in each of the grooves of the inner ring, and a cage (2) retaining the balls. The outer ring (4) has grooves (4a) in its inner surface in which the balls (3) are received and guided. A boot (8) is directly fixed to the outer ring. A circlip (10) is fitted to the inner surface of the outer ring (4) near its open end, to prevent the balls (3) from dropping out. An additional circlip (11) is fitted to the inner surface of the outer ring (4) remote from its open end, to limit the maximum working angle of the shaft (5). <IMAGE>
