A ball joint device (10) for suspension of a turbine machine to a pylon or suspension of a device on the body of a turbine engine. The device comprises a first member (12) one end of which carries a ball (14) and which is inserted between two lugs (16, 17) of a second member (18), the ball having a bore (28) for passage of a pin (30) the ends of which pass through the openings (20, 22) of the lugs. A first lug (16) comprises or carries first means for axial retention of the pin on the side opposite the ball, which has a cover (52, 52'), and a second lug (17) comprises or carries second means (38) for axial retention of the pin on the side opposite the ball. The device further comprises an elastic member (62, 62') which is deformable under compression and which is held by the cover, said elastic member (62, 62') being configured so as to axially bias, in a direction opposite to the cover, a bearing element (40) passed through by the pin and axially bearing on the ball (14). Le dispositif (10) d'articulation à rotule pour la suspension d'une turbomachine à un pylône ou la suspension d'un équipement au corps d'une turbomachine. Il comprend un premier organe (12) dont une extrémité porte une rotule (14) et est intercalée entre les deux oreilles (16, 17) d'un second organe (18), la rotule comportant un alésage (28) de passage d'un axe (30) dont les extrémités traversent des orifices (20, 22) des oreilles, Une première (16) des oreilles comprend ou porte des premiers moyens de retenue axiale de l'axe du côté opposé à la rotule, qui comprennent un couvercle (52, 52'), et une seconde (17) des oreilles comprend ou porte des seconds moyens (38) de retenue axiale de l'axe du côté opposé à la rotule. Le dispositif comprend en outre un organe élastique (62, 62') déformable en compression qui est maintenu par le couvercle, ledit organe élastique (62, 62') étant configuré pour solliciter axialement dans une direction opposée au couvercle un élément d'appui (40) traversé par l'axe et en appui axial sur la rotule (14).
