A plug arrangement for an electric or optical cable includes a connector body connected with the cable and including a first socket or plug. An insulating housing is provided configured to receive the connector body. A locking tab is articulated at a front edge of the connector body and configured to block release of the connector body from a counter body having a plug-in opening and including a second plug or a socket complementary to the connector body. A length of the locking tab is less than or equal to a depth of the plug-in opening. A resilient actuation element is provided including a pressure body extending parallel to a plug-in direction of the plug arrangement. The actuation element is integrally disposed in an articulated manner via a film hinge on the housing so as to be deformable with the housing and actuate the locking tab. The actuation element is integrated in a wall of the housing via at least one surface element disposed on the housing.
