A connector for tubular sections has two elements separable by threaded screws for engaging the interior walls of the tubular sections. The screws are threaded into connectors on one element, and have affixed nuts that engage the other element from inside to separate the elements. One screw has a recessed head so that a tubular section may slide over it. The other projects, to locate the coupling in one of the tubular sections. The projecting screw is located near an end of the coupling element, allowing the other end to be pivotally narrowed for mounting of a tubular section.
