A spray nozzle insert is positioned in the actuator. The spray nozzle insert includes an end wall having a spray orifice therethrough. A cylindrical wall connected to the inner side of the end wall is arranged concentric with the spray orifice. The spray nozzle insert has at least two snap fingers at a radial distance outside the cylindrical wall. The actuator has at least two guiding ribs configured to guide each snap finger upon positioning the spray nozzle insert in the actuator. The snap finger has a snap member which is snapped behind an inward end of the guiding rib.
