Connection for attaching apparatuses such as blowtorches onto sources of gas fuel

摘要

An auxiliary ring 25 is mounted to freely rotate and slide on the body 10 of the connection R. This ring 25 makes it possible to improve the assembly conditions on the cartridges and also the service conditions with cartridges. The ring 25, moreover, makes it possible to mount, without any adapting, the connection R on other types of gas fuel sources, for example household cylinders or camping cylinders. <IMAGE>
