A bimetallic element in which a bimetallic strip of two bands of different metals is wound helically into an elongated body, said body having in its center a free space, the diameter of which is smaller than the thickness of the bimetallic strip and preferably is essentially zero. By winding said elongated body into a helical spring, the outer diameter of which is substantially greater than the outer diameter of the elongated body, an element is obtained that can be used as a thermostatic actuating means in a thermostatic device.
