The present invention is directed to a cable routing system with a bracket that joins adjacent cable trays. The bracket includes a main body having a top edge, a bottom edge, and sides. The top edge includes at least one notch at a center of the main body to retain transverse wires of the adjacent cable trays. The bottom edge includes a spring arm to hold the bracket in place. The bracket is attached to adjacent cable trays with a longitudinal wire of each cable tray positioned between the top edge and the spring arm to secure the bracket to the cable tray.
