1. A fluidic connection and fluid heating device for a fluid circuit, in particular for a motor vehicle, this device comprising:
a one-piece tubular body made of plastic or composite material, the body comprising:
an inlet and an outlet each equipped with fluidic connection means, which are of the press-fit or male/female cooperation type,
at least one internal annular surface defining a fluid flow duct from the inlet to the outlet of the body,
at least one cylindrical or frustoconical surface extending around the duct and defining an outer surface of the body, and
at least one resistive heating element located on and extending around and along the at least one cylindrical or frustoconical surface,
wherein the resistive heating element is a resistive circuit which comprises at least one elongated resistive track whose longitudinal ends are connected to electric connection terminals which are oversized relative to the or each track so as to be connected to electrical wires or lugs, the circuit being secured and formed directly on the at least one cylindrical or frustoconical surface.
