1. A method of manufacturing a temperature measuring device, the method comprising the following steps:
a) supplying a temperature sensor including a measuring cell and two metal branches, the measuring cell having a free first end and a second end secured to the metal branches;
b) providing two electrical connection pins each having an attachment portion and a connection portion;
c) forming an electrical connection between one of the metal branches and one of the electrical connection pins and between the other of the metal branches and the other of the electrical connection pins, at their attachment portions, respectively, the attachment portions of the two pins extending in a main plane, the electrical connections being formed when the first end of the measuring cell occupies a predetermined position relative to a reference point of the electrical connection pins, the first end occupying the predetermined position as a result of a positioning step controlled to better than +/−0.1 mm of the first end relative to the reference point; and
d) assembling a plastic casing formed by at least two inserts positioned against the electrical connection pins, on either side of the main plane, to form an intermediate assembly intended to be overmolded to form the temperature measuring device, the casing defining a clamp to hold the measuring cell along at least one transverse axis normal to the main plane, wherein the clamp of the casing is formed by two flexible arms, each belonging to an insert, and bearing on two areas of the periphery of the measuring cell.
