An electrical connector assembly includes a housing that has an insert and an organizer separate from, and coupled to, the insert. The insert and the organizer have insert openings and organizer openings aligned with corresponding insert openings. The organizer openings have a smaller diameter than the insert openings and the insert openings have a lip that extends into the insert opening. Electrical connectors are received in the housing that have shells and include clips surrounding corresponding shells. The clips engage the lips of the insert openings for securing the electrical connectors in the insert openings. The organizer openings circumferentially surround the shells and restrict lateral movement of the electrical connectors.
