This thermostat (1) comprises a body (10) which comprises a one-piece metal part (11) including simultaneously, in succession along the axis (X-X) of a thermostatic element (20) of the thermostat, a transverse tab (12) against which the piston (22) of this element can bear, a tubular part (13) centred on this axis and defining a shut-off seat (13A), and two support arms (14) supporting a return spring (40) for returning this element, which arms extend lengthwise more or less in the axial direction of the element and each delimits, at their opposite end (14A) to the tubular part, a surface (14A1) for contact with the spring against which surface the compressed spring is pressed. To make it easier to manufacture this body and to assemble it with the other components of the thermostat, each arm is, at its end (14) facing towards the tubular part, connected to the rest of the one-piece metal part in a way that can be deformed between a service position in which the contact surface is plumb with one end of the spring, and an assembly position in which this surface is away from the axis.
