A coupling unit has an electrical-connector for push-fit electrical connection in the coupling unit axial direction to a mating electrical-connector of a unit. The electrical-connector and mating electrical-connector have engagement formations permitting push-fit connection only when the electrical-connector is in predetermined rotational alignment about axial direction with the mating electrical-connector. The coupling unit has a backshell in fixed rotational relationship with the electrical-connector and extending rearwardly therefrom to house, in use, one or more leads extending rearwardly from the electrical-connector. The coupling unit has coaxial actuation sleeve surrounding the backshell. The actuation sleeve axially moves to effect push-fit connection. The backshell and actuation sleeve are operatively connected so: actuation sleeve movement in forward axial direction towards the unit is resisted by electrical-connector contact with the mating electrical-connector to produce backshell rotation, thereby aligning the electrical-connector with the mating electrical-connector and allowing push-fit connection of the electrical-connector to the mating electrical-connector.
