An electric drive for an electric motor. The electric drive is made up of components consisting of a brush holder plate and a bearing plate which are interconnected via at least one snap-on connector with an expandable catch means that is disposed on an external area of an electric motor, a drive motor, or a positioning drive in such a manner that it projects out. The electric drive can be securely mounted and handled in an economical manner without additional components and without complicated manufacturing equipment. This objective is accomplished by the fact that the expandable catch means is protected by a protective device against unintentional expansion of the catch means and thus loosening of the snap-on connector.
