A rod connector for transversely connecting two vertebral column rods has two clamps and a transverse bridge that fixes the clamps to each other. The clamps have a spring device with a spring force that is low enough to allow the clamp to be manually snapped onto the vertebral column rod, to be slid onto the same in the installed state, and to be released from same. An attaching device for the clamp, which is independent of the spring device, generates a retaining force that is high enough to solidly attach the clamp on the vertebral column rod in the installed state. The transverse bridge has a connection part with a frame for receiving a first branch connected to one clamp and with a ball rotatably mounted in the frame and having a second branch pass therethrough that connects to another clamp.
