Abstract
An electric plug-in connector, comprising a plug head on which a union nut is rotatably disposed for screwing the plug-in connector together with a mating connector, can be screwed together with the mating connector under adherence to a prescribed tightening torque even without a torque wrench if the union nut consists of a threaded sleeve with a ring which comes into engagement with the threaded sleeve by way of driving parts at least during screwing on, of which the one driving part is dimensioned in such a way that it is shorn off by the other driving part when exceeding a tightening torque.

An electric plug-in connector comprising:
- a plug head;
- and
- a union nut rotatably disposed on the plug head, the union nut configured to threadingly engage the plug-in connector with a mating connector, the union nut comprising:
- a threaded sleeve including a shearing driving part, and
- a ring including a shearable driving part comprising a tooth-shaped segment, the shearing driving part on the ring further comprising a cutting profile with a blade directed against the base of the tooth-shaped segment,
- wherein the ring engages the threaded sleeve via the driving parts, and wherein the shearable driving part disposed on the ring is dimensioned such that it is shorn off by the shearing driving part disposed on the sleeve upon application of a predetermined torque amount to the ring, the applied torque amount exceeding a predetermined threshold value.
