Abstract
A rebar coupler for connecting reinforcing rods in end-to-end relation including a pair of hollow steel split pipe members having nuts welded thereto. The split pipe members are mounted on the ends of the reinforcing rods and bolted together. The split pipe members are annealed such that when bolted together the deformations on the outer surfaces of the rods embed themselves within the split pipe members to provide a very strong connection.
