A contact clamp for connecting a conductor end with an electrical contact and having an insertion side, from which the conductor end can be inserted in the contact clamp, comprising a retaining frame with a contact section, with which the conductor end can establish a contact, as well as a clamping leg, which is pivotally mounted in the retaining frame and can be pivoted back and forth between an open pivot position and a closed pivot position. The clamping leg runs at an angle to the contact section when in the closed pivot position, and is resiliently movable, such that the conductor end can be inserted in the contact, subject to the elastically spring-loaded opening of the clamping leg, to the target contact position, when in the closed pivot position.
