The spring-loaded clamping connection has at least one clamping point for clamping the electrical conductor which is formed with a clamping leg of a clamping spring. The conductor connection terminal has a manual actuating element which, as a result of manual actuation, can be moved from at least a closed position, in which the clamping point is closed, to an open position, in which the clamping point is open, and vice versa. The conductor connection terminal comprises a movably mounted control element by means of which the manual actuating element is mechanically coupled to the clamping spring, so that, as a result of manual actuation of the manual actuating element, the clamping point can be opened and closed via the control element. ## Claims ### Claim 1 A conductor connection terminal comprising: at least one spring-loaded clamping connection for connecting an electrical conductor via a spring-loaded clamping, the spring-loaded clamping connection comprises at least one clamping point for clamping the electrical conductor which is formed with a clamping leg of a clamping spring;
