- the rail 200 comprises two rectilinear ribs 212 substantially parallel to each other and to the axis C. They are arranged next to each other and are dimensioned and spaced so as to cooperate with the grooves 204 of the slide 202 of the 190. They are intended to be engaged with a small clearance or even with a tight fit in these grooves 204. They therefore have shapes complementary to those of the grooves 204 and are here substantially divergent in the transverse direction of the end piece 28 This makes it possible to ensure retention of the nozzle 150 with respect to the support 190, in a transverse direction on the side opposite to the arm.
- the outer longitudinal ends 212a of the ribs 212 are beveled to facilitate insertion of the ribs into the grooves 204, as shown in Figures 6, 7, 8a and 8b. These ends 212a can be configured to abut on the transverse flange 210 of the support 190 in order to define an end position of the jet 150. with respect to the support 190. The cooperation of these ends 212a with the flange 210 also ensures the translation locking of the nozzle 150 along the axis C, the side opposite to the cannula 152, that is to say say outside.
- the upper flange 208 is intended to be covered by the upper wall 186 of the nozzle 150 in the mounting position ( Figures 7 to 10).

- the recess 214 has an elongated shape along the axis C.
- the tab 182 also has an elongate shape along the C axis and includes a external longitudinal end of connection to the rest of the fixing support 190 and a free inner longitudinal end on which is provided a hooking tooth 216.
- the tooth 216 is projecting on this end and extends in a substantially horizontal plane, on the side of the nozzle 150.
- the tooth 216 has an inner longitudinal end which is tapered and which is intended to cooperate with the ramp 180 of the finger 178 of the push button 170, as can be seen in FIGS. 9 and 10.
