These forces may be up to 100N or more. The fitting installation is often not technically assisted and is not easily accessible because the space available for installation is too small. This means that the contact connection must be made by the hand of the installer and therefore a correctly made plug connection depends on the way the installer works, so that a bad connection due to an unsafe plugging process cannot be prevented due to time and working pressure with fatigue, etc. Insufficient connection results in disconnection of the plug connection, followed by interruption of the transmission during operation.
