A constant velocity joint ( 1 ) comprising: a male element ( 2 ) with multiple arms ( 4 ), a female element ( 8 ) having a central axis (X'-X') and defining tracks ( 9 A, 9 B) which are symmetrical in relation to a radial longitudinal plane (P), and an outer roller ( 12 ) with a rolling surface ( 30 ). The tracks and the rolling surface define two contact points (Z 1 , Z 2 ) therebetween. The tangent planes of the track and rolling surface coincide and are parallel to the plane (P) at not less than one contact point. The cross profiles of the tracks and rolling surface at not less than one contact point are rectilinear or convex.
