A swivel joint assembly comprises a first arm member having a first end joint on one end. The end joint has an arcuate groove thereon. A second arm member has a second end joint on one end. The second joint has stop structure thereon for limiting rotational movement of said swivel joint to approximately 360 DEG . A swivel structure provides rotational movement between the first and second end joints. The swivel structure includes a fastener for securing the first and second end joints to each other. The stop element protrudes into the arcuate groove and a stop shoulder on the arcuate groove co-acts with the stop element to limit rotational movement of the swivel joint.
