Don't know what the coiled wires are like but to refit a connector to the glass I'd use a bit of two part epoxy like Araldite, and to sort the electric connection I'd use some silver conductive paint to link the connector to the heated element. You need to carefully scrape some of the protective paint off the silver track to get a good connection. I've used conductive paint to repair broken heater elements before, but never had to fix one where the connector had come off.
Or after looking in the FSMs, you could use Mopar Rear Window Defogger Repair Kit (P/N 4267922), which is a conductive epoxy. That'd stick it back on and conduct the electrickery to the heater element.
