In a media conducting device which effects a temperature measurement of the medium is used a media conducting pipe 11 with a lateral exit on which is arranged a group of sensors. This component group includes a sensor housing with electric temperature sensor 40 with two contact pins 27, 28 projecting from the sensor housing. In order to develop an inexpensive, space-saving device it is proposed to provide the pipe 11 with a one-piece connecting piece 12. This results in a T-pipe combination 10. The moulded-on connecting piece 12 thus forms the essential part of the sensor housing, whilst the remainder of the sensor housing consists of a stopper 30. This stopper 30 is a constituent part of a plug unit 20 which serves merely as support for the contact pins 21, 22 and the temperature sensor 40 connected thereto. The connection between the plug unit 20 and the connecting piece 12 of the T-pipe combination 10 is effected by means of a simple plug coupling, where the inner section 15 of the connecting piece 12 forms the plug receptacle and the stopper 30 forms the plug-in part of the plug coupling.
