A connector housing includes a housing and a shield. The housing has an interior chamber extending between housing mating and back ends. The inner surface has loading and transition portions, with the loading portion located proximate to the housing mating end and the transition portion located proximate to the housing back end. The shield is shaped to fit in the interior chamber and extends between a shield mating end and a shield back end. The shield back end includes a ground contact opening. The shield includes a rim protruding from the shield back end that extends around a portion of an outer periphery of the shield back end. The rim includes a plurality of rim ends separated by a gap. The rim engages the transition portion to prevent the shield being removed through the housing mating end and the gap exposes a portion of the transition portion.
