To provide a connector which does not protrude into a workspace.SOLUTION: An expandable connector of this invention is a connector to be used for connection of pipe materials (for example, vertical poles constituting a scaffold) and includes a joint tool, and a pipe holding tool provided on at least one end side of the longer direction of the joint tool in such a manner that its length is adjustable. The joint tool is made of a pipe material with a female screw on an inner circumference thereof. The pipe holding tool includes a shaft part which has a male screw able to be screwed on the female screw of the joint tool on an outer circumference thereof, and a single clamp provided on a tip side of the shaft part. The expandable connector is made as such that by changing the length with which the pipe holding tool is screwed into the joint tool, the length of protrusion from the joint tool is adjusted to expand or contract the entire length to a desired length. The expandable connector can also be structured to include the joint tool with the male screw and the pipe holding tool with the female screw.SELECTED DRAWING: Figure 1
【課題】 作業スペースに突出することのない連結具を提供する。【解決手段】 本発明の伸縮式連結具は、パイプ材（例えば、足場を構成する縦支柱）の連結に用いる連結具であって、継手具と、当該継手具の長手方向の少なくとも一端側に長さ調整可能に設けられたパイプ保持具を備えている。継手具は内周に雌ねじを備えたパイプ材である。パイプ保持具は外周に継手具の雌ねじに螺合可能な雄ねじを有する軸部と当該軸部の先端側に設けられた単クランプを備えている。この伸縮式連結具は、パイプ保持具の継手具へのねじ込み長を変えることによって、継手具からの突出長を調整して全体の長さを所望長に伸縮させられるようにしてある。本発明の伸縮式連結具は、雄ねじを有する継手具と雌ねじを有するパイプ保持具を備えた構成とすることもできる。【選択図】図１
