A high-frequency transmission of data between functional units, which are mounted rotatably with respect to each other, of an endoscope, is permitted in which the functional units can be electrically insulated from each other. For this, an electric connecting element which, in a central flexible portion, is rolled up transversely with respect to the direction of transmission and is fastened by its respective end portions to the functional units is provided. An uninterrupted electrical connection with consistent quality of the signal transmission can therefore be obtained even when the functional units are rotated in relation to each other. By the rolling up of the central portion to form a winding, which is preferably configured in a self-supporting manner, a long term stable rotary degree of freedom is created in a very simple manner for the connecting element, with this degree of freedom permitting complex mechanical adjustment functions in the endoscope.
