Abstract: A security bracket for a portable telephone provides locking security for at least the transceiver, battery, and carrying bag of such a telephone installed in a vehicle, while allowing ready access to the telephone handset. An open top container is dimensioned to receive the transceiver, battery and carrying bag, which are locked in place by a hinged, generally U shaped lock bar. The telephone hand set is placed atop and within the U of the lock bar where it also engages the transceiver for normal operation and provides access for ready use at all times. Thus, the security bracket provides deterrence against theft, as the only component readily removable is the telephone hand set, which is of little value without the remaining components which are secured within the container of the security bracket. A base supports the container, the base being securely mounted on the floor of the vehicle. The container may be angularly adjusted with respect to the base for ease of access to the telephone by the user.
