Various embodiments include device housing for an electrical device comprising: an inner housing with a first lower shell and a first upper shell; and an outer housing with a second lower shell and a second upper shell. There is a cable insertion opening defined by a cable seating profile in the first lower shell and a flush cable cover profile in the first upper shell for a cable routed to the device; a clamping body retained by the inner housing; and a friction and/or form-fitting contact between the clamping body and the cable can be effected by means of the outer housing when the clamping body is pressed onto an outer surface of the cable by the upper shell of the outer housing.
