ABSTRACT:
A patch for a ducting wall has two sealing portions, one of which may be bent to pass through a torn opening in the ducting wall. When jointed by a coupling means, the two sealing portions may pinch the ducting wall surrounding the torn opening and provide a barrier against the escape of air through the opening.
