The device makes use of a simple and inexpensive mechanism for temperature stabilization of one or a number of points of an electric circuit such as the free ends of the bimetallic conductors of a thermocouple, or a connector designed to receive one or a number of pins connected to an electric circuit. A good thermal contact is established between the point to be temperature-controlled and a positive-temperature-coefficient resistor which may be surrounded by a second resistor of the same type. The resistors are supplied at constant voltage. One example of the connector consists of a metallic casing surrounding a resistor in the form of a cylindrical sleeve placed around a second resistor in the form of a cylindrical sleeve in which one or a number of jacks are embedded in heat-conducting material.
