A connection of two components is disclosed that abut on the faces thereof. With this connection, it is possible to create a stable connection, particularly of flat components, with a high level of precision of the position with regard to one another and with a preferred accessibility in the space around the plane extending from the adjacent adjoining faces of the components. Both components each have a half borehole with encircling collars; a fastening device that extends through the complete borehole and a nut having a conical recess which rests tightly against the collars so that the first component is fastened to the second component in a positive manner. It is further possible to provide a fastening of guiding elements to a middle base support that, in essence, overlaps the support at least occasionally and is effected by the connection.
