An electrical connector includes a housing (12) and a coupling assembly (35) that has a mateable contact (32) at the front of the housing and a conductor-terminating coupling (34). The coupling has a pair of arms (38, 40) with jaws (48) that are biased toward an axis (37). A holder member (54) has a pair of projections (58, 60) with surfaces that hold the arms in a ready position wherein they have been resiliently deflected away from the axis. When a cable conductor (66) is inserted forwardly (F) through a bore (28) in the housing, the forward tip of the cable presses the coupling assembly forwardly. As the coupling assembly moves forward, the arms are released from the holder members, so the arms can move toward the axis and the jaws (48) on the arms can engage the cable conductor.
