In an aerosol provided with a container for a medium under pressure, and with a spray nozzle which is connected to a medium supply device of the container, and with which the medium can be sprayed after the opening of a valve provided between container and supply device, the spray nozzle and the supply device are provided with fixing devices for irreversibly fixing the spray nozzle on the supply device. For this purpose, the supply device and the spray nozzle can bear barbed fixing devices, in such a way that the spray nozzle can be fitted on the supply device by sliding towards it, but is blocked in the oppposite direction. The parts of the spray nozzle and/or of the supply device determining the flow connection can have a weakened part, which weakened part is broken when the spray nozzle is removed from the supply device, in such a way that the flow connection is damaged.
A dispensing system for a medium which is under pressure, comprising a separately provided spray nozzle for a container which contains said medium, said spray nozzle being adapted to be fixed irreversibly to a supply device of said container, wherein parts of the spray nozzle and the supply device, which together establish fluid communication, have at least one weakened portion to facilitate rupturing upon an attempt to remove said spray nozzle from the container.
