1. A fluid spray nozzle configured to be arranged on a body of a cleaning device for cleaning an optical detection system mounted on a motor vehicle, the fluid spray nozzle comprising:
a base; and
a cover part, wherein the cover part comprises an inclined plane that forms a ramp;
wherein the base and the cover part form an internal distribution duct which extends between a proximal end of the fluid spray nozzle forming an inlet of the internal distribution duct fluidically connected to a fluid distribution canal formed in the body of the cleaning device, and
a distal end of the fluid spray nozzle forming an outlet of the internal distribution duct;
wherein the internal distribution duct is delimited at least by a bottom wall of the internal distribution duct and two opposing lateral walls of the internal distribution duct;
wherein the two opposing lateral walls includes chamfered portions, wherein the chamfered portions are configured to produce a flat jet of fluid;
wherein the chamfered portions of the two opposing lateral walls are in the vicinity of the distal end;
wherein the ramp is arranged in a path of the fluid at a level of the outlet of the internal distribution duct and extends beyond the lateral walls; and
wherein the two opposing lateral walls diverge from one another, in the inclined plane that forms the ramp, as the two opposing lateral walls progressively approach the ramp.
