A device for measuring the temperature in the interior of a vehicle is provided. The device includes an interior temperature sensor arranged at and/or in a plug-in end of a plug-in housing. The interior temperature sensor projects beyond the plug-in end of the plug-in housing. The plug-in housing is biased away from a cover element for assuming a defined plug-in position of the plug-in housing when the plug-in end of the plug-in housing is plugged into a receiving space of the latter and the interior temperature sensor is arranged in the through-going opening of the cover element.
