1. A temperature sensor for a fluid pipe, this temperature sensor comprising:
a body made of plastic or composite material comprising:
a first part configured to be engaged in said pipe and to be in contact with said fluid,
a second part configured to be located outside the pipe, and
at least one fixing bracket configured to cooperate with the pipe and to ensure the fixing of the sensor on this pipe; and
at least one thermosensitive element located on the first part of the body and connected to electrical connection terminals located on the second part of the body;
wherein the first and second parts are made in one piece and the first part of the body comprises at a free end a flat surface which is located outside the body so as to be in contact with the fluid and on which is located a track forming said thermosensitive element, this track having a generally elongated shape and comprising opposite ends connected respectively to said terminals by electrical conductors embedded in said body and extending continuously from said free end to the terminals.
