Abstract: A connection element for electrically connecting a circuit carrier to another circuit carrier includes at least one solder connection for soldering onto the surface of the circuit carrier and a connection pin, which is electrically connected to the solder connection, for inserting into the other circuit carrier. The connection element has a holding body and a contact element which is connected to the holding body and which is designed to be elastic. The contact element has an end section, the solder connection being formed on the end section. The connection element has a locking element which is connected to the connection element in a movable manner back and forth between a locking position and a release position. The locking element is designed to limit the displacement of the contact element in the locking position and release an elastic movement of the contact element in the release position.
