One of the two wires that power the glass rear window defroster has come loose. Trouble is, the connector didn't just slide off its metal tab. The tab itself has broken off from the glass, leaving the wire to dangle free and nothing solid to connect it to.

I don't want to solder a new tab directly onto the glass, so I'm thinking of using some sort of conductive adhesive to repair it. Does anyone have any better ideas before I do something irreversible?
