Abstract
A device for releasing a gas to a respirator with a compressed gas cylinder (2), which contains the gas and has a metering valve (6). The metering valve (6) can be opened by pressure. The metering valve (6) has a tubular valve body (7) letting through the gas and has a collar (5) surrounding the valve body (7). A cylinder adapter has a locking mechanism (16) designed for fastening to the collar (5). The cylinder adapter (1) always remains associated with the corresponding compressed gas cylinder (2). This is accomplished by a predetermined breaking point with reduced strength properties being provided on the cylinder adapter (1). The breaking point is intended to destroy the locking mechanism (16) during the removal of the cylinder adapter (1) from the collar (5).
