Abstract:
The invention pertains to an adaptor for inserting lamps with pin bases into screw bases, the task of which is to make it impossible to screw out the adaptor without special tools after it has been inserted into the screw base. This task is achieved by the invention by arranging the thread of the adaptor on a loosely rotating threaded bushing which can be rigidly connected with the adaptor body by means of a key before screwing in the adaptor. After the adaptor has been screwed in and the key has been removed, the threaded bushing cannot be removed from the socket.
