A connection terminal having at least one busbar piece and at least one clamping spring. The connection terminal has at least one spring-force clamping connection formed from a clamping spring and a portion of a busbar piece, an insulating-material housing including at least one conductor insertion opening which leads to an spring-force clamping connection and extends in a conductor insertion direction, and at least one pivotably mounted operating lever designed to interact with at least one clamping spring in order to open at least one spring-force clamping connection. The operating lever can be arranged with its rotation axis in the conductor insertion opening or in the path of the conductor insertion opening in the direction of the clamping point. The connection terminal provides a space-saving and compact construction, which is also improved in respect of the force effect of the operating lever.
