The terminal also includes a busbar, a clamping spring arranged in the chamber and acting as a compression spring for fixing the electrical conductor on the busbar in the area of a clamping site. The clamping spring includes a pivotable clamping arm which can be adjusted from a locked state in a locked position into a clamping state in which it is unlocked from the locked state and presses the electrical conductor against the busbar. An actuation element which is movable in the housing is provided which, together with the clamping arm of the clamping spring, can be locked in the locked state. The mobility of the actuation element in the housing in the locked state can be arrested by a locking element which is movable at an angle relative to the movement direction of the actuation element.
