Abstract

Abstract Apparatus is provided for moving a plug fitting relative to a hole in a conduit. A housing is mounted on a conduit over a fitting to be removed. An aligned drawbar mounted on the housing, is descended and interlocked with the fitting. The fitting is withdrawn from the hole and moved to an out-of-the-way position. A rod holding a second fitting is slidably mounted within the drawbar to descend, insert and release the second fitting when properly inserted in the hole.
