The connecting terminal is intended for a built-in appliance for installation in a row, especially for a line protection circuit breaker. It has two plates (3, 4) for clamping onto a busbar (1) of an electrical service installation, as well as a screw connection having a screw (6), which can rotate and acts on a moving (3) one of two clamping plates (3, 4), in order to produce the clamping force. Furthermore, a guide device is provided for guiding a sliding body of the moving clamping plate (3). The guide track (7) has two sections which merge into one another, of which, when the screw connection is released, a first section (8) which runs essentially in a straight line is used to push the moving clamping plate (3) off the busbar (8), and a second section (9), which is arranged inclined at an obtuse angle with respect to the first (8), is used for pivoting the moving clamping plate (3) which is pushed off the busbar (1). The second section (9) of the guide track (7) runs in the form of a spiral which, in particular, is logarithmically curved. The origin of the spiral is located on the rotation axis of the moving clamping plate (3) in the case of the pivoting movement design. Such a connecting terminal is distinguished by simple construction and can be tightened and released very quickly. In addition, it can absorb very high tightening torques and is thus particularly suitable for clamping conductors which carry heavy currents. <IMAGE>
