The plug connector (2) and the mating plug connector (3) can be plugged together in order to form the plug connection (1), wherein the plug connector (2) has a contact support (4) with at least one contact chamber for receiving a contact partner, and the contact support (4) is inserted into an outer housing (5) of the plug connector (2). Each contact partner is primarily locked in the contact chamber of the contact partner, and a secondary lock (6) is provided for a secondary locking of the contact partners in the contact chambers thereof. The invention is characterized in that the secondary lock (6) is formed by a longitudinal web (16), at the two ends of which a respective latching element (17) is arranged that interacts with the contact support (4), and at least one force absorbing web (19) is arranged on the upper face of the longitudinal web (16).
