1. A thermostatic cartridge, comprising:
a housing,
a base, which is attached to the housing and which encloses a chamber for mixing a cold fluid and a hot fluid, this chamber being connected to outside of the base by a first inlet (16) for the cold fluid, by a second inlet for the hot fluid, and by an outlet for a mixture of the cold and hot fluids,
a thermostatic control system, which is at least partially arranged in the chamber and which is adapted to control the temperature of the mixture to a set temperature, by inversely varying respective flow sections of a first passage, provided between the first inlet and the chamber, and of a second passage, provided between the second inlet and the chamber, and
a flow control system, which is adapted to control a flow rate of the mixture from outside the housing and which comprises:
a control member, which is arranged inside the housing so as to channel both the cold fluid sent to the first inlet and the hot fluid sent to the second inlet, and which is at least partially movable relative to the housing so as to vary both a flow rate of the cold fluid sent to the first inlet, and a flow rate of the hot fluid sent to the second inlet,
an adjustment ring, which is arranged outside the housing and which is centered on an axis around which the adjustment ring is able to rotate relative to the housing, which adjustment ring has a first axial end and a second axial end, which are opposite to each other along the axis, the second axial end facing the control member, and which adjustment ring is provided with a slit, which connects the first and second axial ends to each other and which has edges spaced apart from each other in a direction peripheral to the axis, the adjustment ring being deformable by relative spacing of the edges of the slit in said direction peripheral to the axis, and
a connecting member, which connects the adjustment ring to the control member through the housing so that the rotation of the adjustment ring about the axis causes the control member to move,
and wherein the slit of the adjustment ring includes a notch which is adapted to receive a finger of the connecting member in a clamped manner along said direction peripheral to the axis when the adjustment ring is in an operational configuration.
