The nozzle (18) is fixed to the end of a metal tube (16) itself connected to the outlet (14) of the valve body (8). The pipe (15) is connected, on the one hand, to the inlet (13) of the valve body (8) and, on the other hand, to a container containing a treatment liquid and equipped with a pump so that the volume of air located above the liquid in the container may be pressurised. When the handles (4 and 5) of the secateurs are brought together, the roller (11) presses the push member (10) which opens the stopper member of the valve (8) and puts the inlet (13) in communication with the outlet (14).
