In the device in a hollow space (3) in the accessory (1) is an air bag with an excess pressure. The hollow space has one or more outlet openings (6) which are closed by means of a membrane (7), which can be broken by a pressure thrust. The air bag only partly fills out the hollow space (3) and its remaining space around the outlet openings (6) is filled with a medium, (8) such as a powder or a gas, which is irritating to the eyes and/or skin. - In the device is included a pin (9), which can be pressed through the air bag (2) wall to release excess pressure to cause the air to break the membrane (7) and press out the medium (8) through the outlet openings (6). |
