An extensible handle assembly for a ratchet wrench or similar tool includes a tubular handle member with a central hole down its length and a tool-engaging shank extending through the central hole of the handle member. The shank is slidable in the handle member between extended and retracted positions, and includes a detent to engage the shank at each of those positions. A plug that extends through the central hole from the rearward end of the handle member permits disassembly of the shank from the handle member, restricts movement of the shank outwardly from the forward end of the handle member and restricts axial rotation of the shank.
