Coupling pins for connecting weapon components are described. The network management system comprises least one monitoring apparatus adapted to determine the state of network links. An inner surface of the base portion is in electrical contact with the conductor side opposite the groove, and the outreaching wings are curled about the conductor and extend into the groove. One of the parameters and the core temperature are estimated such that a difference is minimized between the temperatures indicated by the sensor elements, and the temperatures resulting from the dynamic model at the first and second sensor elements for a plurality of time points which lie temporally prior to a specific time point. Within the monitoring housing is a computer with memory. The control unit actuates the actuator as a function of the existence of a predetermined signal so that the actuator brings the locking system in a locking position.
