BOTH sides finished with 10-men as Bangor gifted Connah's Quay three vital points.
In the first-half, a Tom Harrison free-kick hit the bar and Ben Heath was forced to clear a Paul Roberts effort off the line as the Citizens pressed.
With 20 minutes left, Nomads' Phil Molyneaux launched a long thrown from the right and Paul O'Neill headed it clean over keeper Andrew Price and into his own net.
Mike Linnecar was lively up front for City and, wity better luck, could have grabbed a hat-trick.
Martin Beattie was the first player to walk after handling a goal-bound effort on the line and could have few complaints after escaping punishment when upending Stuart Rain in the box in the first-half.
Chris Williams stepped up to convert the spot kick and seal the victory, but followed Beattie down the tunnel two minutes later after a clash with Linnecar.
