A connector assembly for releasably securing a welding torch to an extended end portion of a power cable assembly having an outer hose disposed about an electrically conductive cable for directing gas therethrough to the torch. An aperture is provided in the side wall of an electrically conductive tubular member between upstream and downstream portions thereof. An upstream portion of the tubular member is crimped about an end of the cable so as to define a generally U-shaped trough extending along the upstream portion of the tubular member, creating a gas flow path extending therealong to and through the aperture, into and through the downstream portion of the tubular member. A hose attachment sleeve is rotatably and sealably mounted on a pair of axially spaced sealing members on the downstream portion of the tubular member so that the torch can be rotated with respect to the hose during use, reducing strain on the welder.
