A coupling device is for coupling an optical fiber to an optical transmitting or receiving unit. The coupling device can be included in a transmitting or receiving device. The coupling device to be can be one piece, formed of a nonconductive material, and, for the optical transmitting or receiving unit, can be mounted directly on a section projecting like a step or a contact-making face applied thereto. The flattened surface of the section projects like a step and has a longitudinal notch for positioning the transmitting or receiving unit.
