A tool such as a garden cultivator, squeegee, or paint-roller holder has a relatively short handle provided at its rear end with a relatively deep backwardly open recess. An extension handle has a relatively long front end engageable relatively far into this recess and is provided with a fixed ring formed with a multiple screwthread engageable with a similar formation inside the recess so that the two parts can be locked together by a single revolution relative to each other. At its rear end the extension handle is provided with a cap having a forwardly directed end and screwthread formations similar to that of the front and of the extension handle so that this cap can be placed on the rear end of the short handle of the tool if desired.
