Abstract: A connection device comprises at least one direct-plug-in clamping connection which has a direct-plug-in design for plugging in an electric conductor and which has a clamping spring, busbar and/or a clamping cage. The clamping spring is designed to clamp an electric conductor plugged into the direct-plug-in clamping connection to contact the busbar and/or the clamping cage in an electrically conductive manner. The direct-plug-in clamping connection additionally has an actuation mechanism which can be moved from a base position to an actuation position and back. In the actuation position, the actuation mechanism moves the clamping spring so as to release the electric conductor, wherein the actuation mechanism has at least two actuation regions which are provided for an actuation tool and which are arranged at an angle greater than 0 ° relative to each other.
