Embodiments of the present invention provide a seat belt retainer for a vehicle, the retainer comprising a body having an opening, the body being configured for attachment to a support. An actuator is mounted within the opening, the actuator being moveable within the opening for actuating a seat latch mechanism. A guide is supported by the body, the guide defining an at least partial aperture for receiving a seat belt therethrough. The actuator and the guide are at least partly aligned along the longitudinal axis of the seat belt passing through the aperture, in use.
