Abstract: A sprinkler device, especially for units for the spray distribution of water and other similar liquids, comprising an at least partly hollow central body defining a longitudinal axis, a connecting sleeve to a supply line removably secured to the central body, a convergent nozzle to accelerate the liquid located between the central body and the sleeve, a diverter unit located downstream from the nozzle to divert the flow in a substantially transverse direction so as to spray the fluid outwards, first snap means to connect the nozzle to the sleeve. The first snap connection means are arranged so as to hold the nozzle in an axially immobilised position with respect to the sleeve when the latter is fitted to and disconnected from the central body.
