Abstract
A draw spring clamp has loopshaped draw springs with an attachment leg to contact a current bus and with a spring leg and clamping leg, whereby the latter is interrupted by a clamp window in order to form the clamp leg. By means of an actuation element into which a tool blade may be inserted, the spring leg of the draw springs may be loaded with tension in order to open the clamp window. This actuation element is located between the two spring legs of the draw spring that oppose each other. In order to enable time-saving actuation, the actuation element in its loaded position also rests against the two spring legs. Thus, the actuation element possesses rest positions on its opposing exteriors whose separation increases along a first direction of travel of the actuation element and decreases along the second, direction.
