Abstract

The tool is assembled of a handle and a ratchet head (10) with an inner space for the accommodation of the ratchet (20), which is provided with teeth at the outer surface (21) and a polygonal inner space (22) in order to envelop the screw head to be tightened or loosened. The new design of a ratchet (20) is fitted with at least one tongue shaped spring element (32) attached to the inner surface (22) in order to ensure a firm connection between the screw head and the inner surface (22) of the ratchet (20).
