• a plug insertable into the recess, the plug having a top surface, a bottom surface and a sidewall, the top surface including at least one access hole, the at least one access hole operatively arranged to allow passing first and second ends of the wire from locations exterior of the seal into the recess, the sidewall of the plug having a groove therein, the groove extending at least partially around a perimeter of the sidewall, the groove in the sidewall of the plug operatively arranged to be disposed opposite the groove in the sidewall of the recess when the plug is inserted into the recess;
• and,
• a snap ring having a top surface a bottom surface an inner diameter, a width, and a thickness, the width of the snap ring operatively arranged to be disposed partially within the groove in the plug and partially within the groove in the recess thereby securing an inserted plug to the body, the snap ring having first and second through-holes extending through the thickness of the snap ring, the first and second through-holes operatively arranged to allow the first and second ends of the wire to pass through the snap ring, the first and second ends of the wire further adapted to be foldable over the outer diameter of the snap ring, there being one or more serrations disposed on the outer diameter of the snap ring, the one or more serrations operatively arranged to compress the first and second ends of the wire folded over the snap ring against the sidewall of the recess, thereby securing the first and second ends of the wire within the body of the seal.
