ABSTRACT:
The invention relates to a handset for a radio telephone system, having a front housing shell (2) and a rear housing shell (1) which can be connected thereto. The handset has in its interior a locking device (22, 23) which, in a locking position, locks the housing shells (1, 2) to one another and, in an unlocking position, releases the locking. In addition, the handset also contains in its interior a blocking device (30, 32) which prevents the locking device changing over automatically from the locking position into the unlocking position. Activation of the blocking device (30, 32) is possible only in a way which is as a rule difficult to discover.
