Claim:
An installation for filling an aerosol container ( 12 ) with liquid, comprising: one frame ( 1 ), means ( 3 A, 3 B) for holding, in a removable manner, a scoop ( 10 ) of liquid for filling on the frame ( 1 ) at a mount point ( 4 ) that is located above the point ( 5 ) where the aerosol container is mounted, generally in a position of contact with a valve of said aerosol container ( 12 ), a pushing element ( 6 ) with a removable piston head ( 7 ), and means that indicate when the piston head ( 7 ) is not attached to the pushing element ( 6 ), wherein the pushing element ( 6 ) is moved axially in said scoop ( 10 ) to bring about, by pushing on said liquid, a transfer of this liquid through an opening ( 11 ) of the scoop, into the aerosol container, whereby the removable piston head ( 7 ) is disengaged from the pushing element ( 6 ) inside the scoop ( 10 ) before the pushing element ( 6 ) is withdrawn from said scoop ( 10 ), wherein the means that indicate when the piston head ( 7 ) is not attached to the pushing element ( 6 ) assume a shape of a movable stop ( 8 ) between an active position, in which said stop ( 8 ) is placed on a trajectory followed by said scoop ( 10 ) during installation of said scoop ( 10 ) in the mount point ( 4 ) on the frame ( 1 ) and prevents said installation and an inactive position, in which said stop ( 8 ) allows said installation, wherein the stop ( 8 ) is returned to the active position, is held in the inactive position by the piston head ( 7 ) in an attached state of the piston head ( 7 ) on the pushing element ( 6 ).
