A clamp assembly for maintaining two rod sections parallel to each other includes a collar encircling a longitudinal axis for receiving a first rod section, and a retainer attached to the collar. The retainer has a first hook and a second hook. The second hook for receiving a second rod section is attached to the collar and the first hook is connected to the second hook. The clamp assembly has an open configuration in which the retainer hinges from the collar, and a closed configuration in which the first hook at least partially surrounds the collar. The collar includes a band for encircling the first rod section. The band has a first circumferential end and an opposing second circumferential end that meet to form a closure.
