Abstract: A system for connecting a spinal osteosynthesis rod and a crossbar include a passage for receiving the crossbar and hinge mounted jaws for clamping the rod. A locking device biases the crossbar against the jaws. A return spring pulls the jaws relatively close to one another independently of the crossbar such that the jaws may clamp the osteosynthesis rod to ensure a stable mounting of the connection system to the osteosynthesis rod.

Abstract: A device for transverse spinal connection, comprises a transverse bar (4) secured to at least one spinal osteosynthesis rod (2) with a connecting/blocking member (5) between the transverse bar and the osteosynthesis rod. The transverse bar and osteosynthesis rod are adapted to be connected to each other in situ by the connection/blocking device which is constituted of a first part (6) in the shape of a jaw (8), provided with a passage (10) for the transverse bar (4) and a blocking screw (22) adapted to project into the passage. The connecting/blocking device also includes a second part (7) in the form of an oppositely directed jaw (18) pivoted on the first part (6). The bar (4) in place in the passage (10) being adapted, during screwing in of the screw (22), to come to bear both against the first part (6) and against the second part (7) and to cause the two jaws (8, 18) to move toward each other.
