Thanks everyone for the suggestions. I have look through way to many catalogs now trying to find a match. Since there are no markings on the plug or socket I can only guess that this a "made in china" knock-off and not to spec connector. Most of the connectors in the catalogs look to be of higher quality. I even stopped at a local professional electrical supply store and they could not identify it.

I also sent email with the photos to Mouser sales department and they call me back stating that they have forwarded it on to the tech support. So I hope to hear back from them in the next couple of days.

If a replacement plug can not but be found, I am can going to just solder the pins back on the cable and silicon them into place. Then to untwist the cable, I will turn the transformer instead of disconnection the cable.
