The ball joint device (10) for suspending a turbine engine from a strut or suspending equipment on the body of a turbine engine. Said device comprises a first member (12), one end of which carries a ball joint (14) and is interposed between the two lugs (16, 17) of a second member (18), the ball joint comprising a bore (28) for the passage of a shaft (30), the ends of which shaft pass through openings (20, 22) in the lugs. A first (16) of the lugs comprises or carries first means for axially holding the shaft on the side opposite the ball joint, which means comprise a cover (52, 52′), and a second (17) of the lugs comprises or carries second means (38) for axially holding the shaft on the side opposite the ball joint. The device further comprises a resilient member (62, 62′) that is deformable under compression and is held by the cover, said resilient member (62, 62′) being designed to bias a support element (40), through which the shaft passes and which is in axial abutment on the ball joint (14), axially in a direction away from the cover.
