a nipple coupled to an inner portion of said annular tear stop member so that said nipple is able to seal against smaller diameter electrical cable ends, and so that said annular tear stop member is able to be selectively torn and seal against larger diameter electrical cable ends.
12. The cable end seal according to claim 11 wherein said nipple depends from said annular tear stop member into a respective cable-receiving passageway.
13. The cable end seal according to claim 11 wherein said annular tear stop member and said nipple are integrally molded as a monolithic unit.
14. The cable end seal according to claim 11 wherein said cable end seal further comprises an outer ring-shaped body surrounding an outer portion of said annular tear stop member.
15. The cable end seal according to claim 11 wherein said nipple comprises a tubular body portion and an end portion coupled thereto.
16. The cable end seal according to claim 15 wherein said nipple further comprises at least one concentric rib carried by said end portion.
17. The cable end seal according to claim 11 wherein said nipple has a rupturable membrane at a center thereof.
18. The cable end seal according to claim 11 wherein said nipple has an opening at a center thereof.
19. The cable end seal according to claim 11 wherein said cable end seal comprises a silicone material.
20. A method for making an electrical connector for a plurality of electrical cables comprising:
forming an electrically conductive body having a plurality of spaced apart cable-receiving passageways for receiving respective electrical cable ends therein, and having at least one respective fastener-receiving passageway intersecting each of the cable-receiving passageways;
