A homokinetic joint includes rollers mounted to swivel on the spherical ends of arms of a tripod element by means of free diabolo-shaped rolling elements. Three pairs of runways are provided in a bowl element for the rollers. These runways are curved in planes parallel to an axial plane of the bowl element. Two floating rings maintain the mean planes of the rollers parallel to one another. The tripod element is in this way axially retained in the bowl element by the retention of the rollers in the runways axially of the bowl element by a combined effect of the curved shape of the runways and the maintenance of the mean planes of the rollers parallel to one another, with no need for other devices. This joint is compact, highly efficient, and has a high torque-transmitting capacity and a large break angle.
