A connecting device for spinal osteosynthesis has an osseous anchoring device, a connector that accommodates a joining shaft and is fixed to one end of the anchoring device, and a tightening device for immobilizing the joining shaft. The connecting device is characterized in that the connector is fixed to the anchoring device with the aid of a pin that penetrates the anchoring device and embodies a pivot joint. Furthermore, the device comprises an arrangement for stabilizing the connector relative to the anchoring device when the device is implanted in the patient, the stabilizing arrangement being located on the plane encompassing the shaft and the anchoring device.
