Abstract
Protective gas mouthpiece for a connection device, having a base member which has an axial opening and a mouth arranged around the opening and which can be placed on a workpiece on which a connection process is intended to be carried out, wherein the opening adjacent to the mouth defines a cleaning space into which protective gas can be introduced and which, when the connection process is carried out, can be axially delimited by the workpiece which covers the opening. The protective gas is introduced into the cleaning space in such a manner that a main flow direction of the protective gas in a radial centre of the cleaning space is orientated in a substantially radial and unidirectional manner.
