In the osteosynthesis device of the invention, the elastically deformable connection system comprises: a deformable connection member presenting: in a "sagittal" plane, determined stiffness for exerting a return force on flexion-extension movements between the fixing portions; in a "frontal" plane perpendicular to the sagittal plane, determined stiffness for exerting a return force on lateral inflexion movements between the fixing portions, the stiffness of the deformable connection member in the frontal plane being less than its stiffness in the sagittal plane; and along an axis defined by the intersection between the sagittal and frontal planes, determined stiffness for exerting a return force on traction-compression movements between the fixing portions; and means for limiting flexion-extension, traction-compression, and lateral inflexion movements between the fixing portions.
