Abstract
The plug connection comprises an elastomeric shroud having a plug-receiving portion through which is connected a spark plug comprising an hexagonal handling nut. A metal shield, comprising a top cover portion and two side-shield portions, covers the elastomeric shroud. When mounted, the side-shield portions surround the plug-receiving portions and form joint seam zones, each having a bottom end portion and a top portion. The bottom end portion of one seam zone includes an opening and the bottom end portion of the other seam zone includes a corresponding tab. The side-shield portions further comprise flanges. When the plug connection is connected to the spark plug, the flanges fit onto the hexagonal handling nut and the opening and tab are loosely fitted, so that the joint seam zones can be spaced apart. Preferably, the top portion contains protrusions provided on the side of the side-shield portions and a corresponding recess provided on the side of the top shield, these protrusions and recess fit together when the shield is mounted.
