An electrical connector that includes a connector body having an inlet end and an outlet end that slopes downwardly toward the outlet opening that is circumscribed by a complementary frustro conical outer snap-fit retaining ring mounted on the outlet end of the connector body. The outer frustro conical retaining ring is integrally formed from a blank of spring steel having integral locking and grounding tangs blanked or formed out of the plane of the blank. The connector assembly also includes an internal sleeve having inwardly formed spring fingers to secure an electrical conductor to the inlet end by a snap fit. In an alternate embodiment, a simple clamp arrangement is substituted for the internal snap fit sleeve for securing a wire conductor to the inlet end of the connector assembly. In another embodiment, the connector assembly includes a connector body having complementary body sections, one of which includes a leading end, with the complementary body sections defining a trailing end having multiple chambers for accommodating a wire conductor retaining sleeve within the respective chambers whereby multiple conductors can be secured to the connector body with a snap fit.
