An optical plug connection for optical waveguides including a plug and a matching socket, and also a method for adjusting the plug connection. In the case of such a plug connection, the plug has at least one planar, smoothed contact area oriented with respect to a propagation direction of a light beam passing from or into the plug, for bearing on a corresponding planar, smoothed mating contact area of the socket that is oriented with respect to the propagation direction of the light beam.
