  • Publication number: 20110294321
    Abstract: An electrical plug connector includes a first plug having a first clip and a second clip, and a second plug including a catch element, first and second releasing tabs and an unlatching element. At least one of the first clip and second clip is configured to engage the catch element. The first and second releasing tabs respectively contact the first and second clips in a plugged state of the electrical plug connector and are configured to release the respective clip from the catch element. The unlatching element surrounds the first and second releasing tabs in the plugged state of the electrical plug connector so as to contact the first releasing tab on a first side and to contact the second releasing tab on an opposing side. The unlatching element is displaceable in a direction transverse to a longitudinal axis of the electrical plug connector.
