<p>A fastener 10 for fastening a welding nozzle to a gas output device, the fastener 10 comprising: a first clamping member 12 and a second clamping member 14, moveable between an open configuration and a closed configuration, and which define an aperture 24 for receiving the welding nozzle, the first clamping member 12 including: a member 34 for resiliently engaging the welding nozzle, wherein the member 34 is arranged to be progressively deformed by the welding nozzle as the first clamping member 12 and second clamping member 14 move from the open configuration toward the closed configuration, and is arranged such that the degree of deformation of the member 34 by the welding nozzle achieved when the first and second clamping members 12, 14 reach the closed configuration is equal to, or less than, the maximum resilient deformation of the member 34.</p> |
