Cleaning device intended to spray at least one fluid towards a surface to be cleaned of a motor vehicle, such as an optical surface of a sensor of an optical detection system

A cleaning device to spray at least one fluid toward a surface to be cleaned of a motor vehicle comprising an optical surface of a sensor of an optical detection system, said cleaning device comprising:

• at least one conveying body and a delivery manifold for one or more cleaning and/or drying fluids;
• and
• means for attaching a coupling portion of the delivery manifold to an end of the conveying body,
• wherein the attachment means comprise an elastic interlocking assembly and a foolproofing assembly formed respectively by elements borne by the conveying body and complementary elements borne by the delivery manifold,
• wherein the elastic interlocking assembly and the foolproofing assembly are complementary assemblies jointly coupling the delivery manifold and the conveying body,
• wherein the elements forming the elastic interlocking assembly comprise at least a first snug and a second snug arranged on the conveying body and a first window and a second window arranged in the coupling portion of the delivery manifold, these elements being configured so that the first snug cooperates specifically with the first window and the second snug cooperates specifically with the second window, and
• wherein the elements forming the elastic interlocking assembly are configured in pairs to also perform a foolproofing function of the foolproofing assembly.
