I can’t recall how thick that part is, but I would epoxy the ends, let that set, drill two 0.4mm holes either through the side or from the top about 1.5mm away from the break. Thread brass wire in a loop through both holes pulling it tight. Fold the ends toward each other and trim them off. Bend them side by side to each other, add a drop of flux and an instant touch of the soldering iron having a drop of solder to flow.
