摘要： A tool head has two spaced opposite sides and a stepped opening including a smaller-diameter first portion of non-circular crosssection which converges from one toward the other side, and a larger-diameter portion extending from the other side to and in alignment with the first portion. An end portion of a handle is received matingly in the first portion and an end face of it faces the section portion. A threaded pin is anchored in the end portion of the handle and has a part projecting into the second portion of the opening, with an elastic tubular bushing matingly received in this second portion and with clearance surrounding this part of the pin. Threaded retaining means meshes with said part in the clearance and bears against the bushing at the other side thereof.
