A locking connector is provided for electrically interconnecting first and second electrical conductors. The connector includes an enclosure that accommodates an electrical contact component electrically interengaged with the first conductor. At least two spring locking clips are mounted in the enclosure and serially arranged to face away from the inlet such that the clips are sequentially and resiliently opened by introducing the second conductor into the enclosure through the inlet. The clips are spring biased to grip the second conductor at a plurality of locations and hold the second conductor in electrical interengagement with the contact component. This enables the second conductor to resist disengagement from the contact component.
