A connector system includes a connector body defining a terminal cavity and a first and second groove each extending along an outer surface of the connector body and a terminal retainer attached to the connector body and moveable from a pre-staged position to a staged position. The terminal retainer retains a terminal within the cavity in the staged position. The terminal retainer has a base, a pair of first cantilevered arms extending from the base, a crossbar extending between the first arms defining a first latch feature, and a second cantilevered arm extending from the crossbar. The second arm is between the pair of first arms and defines a second latch feature. The first latch feature engages the first groove in the pre-staged position and the second groove in the staged position. The second latch feature engages the first groove in the staged position.
