<p>A conventional T-Y joint of a fume-extracting welding gun is constructed of two semi-circularly contoured parts which are snap-locked together along a longitudinal line of joint. One part may have a cylindrical portion integrally formed therewith to form an end closure for the joint. The end closure has bores for utility feeds therethrough, with that for the power cable being provided with an integrally-formed hexagonal recess to receive a hexagonal nut on the power cable to enable the power cable to be clamped to the joint.</p> |
