Abstract

A coupling for a compressed gas cylinder (2) includes a separate coupling part (12) that can be screwed to the standardized fitting (3) on the cylinder valve (1). The connection to the coupling means (7) of a pressure reducer (6) or the like is provided by plug-and-socket-type connecting means that can be plugged into each other, interlocked, and closed off by means of locking elements to prevent contamination from outside, the locking element provided on the coupling part at the same time forming a blow-off protection that allows only a limited gas flow when the cylinder valve is opened in uncoupled condition.
