A connecting ring which is screwed with a collar in a passage of a tool handle provides a connection of the tool handle with an extension. The edge of the collar is provided with locking teeth and the interior wall of the tool handle in the passage is provided with locking projections. On screwing in the collar in the passage of the tool handle the locking teeth come into engagement with the locking projections to form a locking seat for the collar in the tool handle by motion in the circumferential direction around the tool handle. This secures the screw connection from undesired loosening. In the same way as the connecting ring can be secured to the tool handle also the cap closing the passage can be secured in a locking seat when the extension is removed from the handle and is not used.
