Locking members are provided on selected faces of the housing to prevent relative movement of matingly engaged housings. The housing is further provided with a flash lamp and a connector and associated circuitry to enable a photographic power supply to be connected to the housing for energization of the flash. An optional adapter cord allows the unit to be powered by power supplies of domestic as well as foreign manufacture.
