A device for connecting sucker, or drive rods, consisting of a threaded coupling, one end of which has a right hand female thread and the other a left hand female, which joins the threaded pins of adjacent rods. The ends of the pins are equipped with dogs, or lugs, that interlock when the connection is made up, firmly linking the rods torsionally. The coupling serves only to keep the dogs, or lugs, engaged and to carry the tensional load on the connection. Such a connection provides a stronger torsional link between rods than connections currently available. The connection also does not require the special make-up procedure of the current systems and cannot over tighten or back off during operation.
