A locking pipe joint assembly, device and method can employ a center body connector, one or more sealing elements, such as a wiper seal and a sealing ring, a sealing ring retainer and a retaining cap. In various embodiments, primary and secondary fastening rings are employed along with a retaining cap sleeve. In embodiments, the retaining cap includes an internal or external thread that mates with an external or internal thread on one side of the center body connector, which allows the retaining cap to tighten the packing arrangement components around an inserted piping or tubing element, and in secure engagement with the interior of the center body connector. In embodiments, a bolt element is provided for further securing of the retaining cap to the center body connector.
