A sprayer includes a container of product to be sprayed, provided with a delivery opening for this product, and a spraying assembly. The spraying assembly is in fluid communication with the delivery opening and is securable onto the container by insertion about a mounting axis. The spraying assembly includes a sprayer body delimiting a proximal area conformed so as to be securable to the container, and includes a distal wall, transverse to the mounting axis, in which a spraying aperture is arranged, and a cap intended to be mounted on the sprayer body. The cap includes a wall transverse to the mounting axis, which is sufficiently rigid so as to bear, without substantial damaging, a force from 50 to 100 N necessary to secure the sprayer body to the container and thus to enable the transmission to the sprayer body of this force.
