It is intended that a radio transceiver for mobile radio systems can be inserted, removed and securely locked in simple fashion in a holder fixed in the boot of a vehicle, the electrical connections being able to be established automatically in a simple and operatively secure manner. The holder is furthermore intended to be able to be manufactured simply and cheaply and to be used even in confined spaces. It is proposed that the holder is designed as essentially parallelepiped-shaped and has at least one supporting strip on its lower periphery to support the radio transceiver. To establish the electrical contacts, at least one multiple mating connector part is provided which can be coupled with the multiple mating connector part of the radio transceiver. A locking hook mounted on the upper periphery of the holder engages in a locking aperture of the radio transceiver. Mobile radio systems.
