A quick coupling for coupling a tool to the boom of a hydraulic excavator and the like with a quick coupling part on the boom and a quick coupling part on the tool which can be latched together by means of two spaced latching axles and with a power coupling, for example a hydraulic coupling, for the automatic coupling of a power circuit on the tool to a power circuit on the boom. The power circuit coupling has a power coupling part on the boom and a power coupling part the tool which are arranged such that they automatically couple as soon as the two quick coupling parts are pivoted together into their latching position about a first of the two latching axles. A linear guide means is associated with the power coupling which guides the two power coupling parts in a linear manner with respect to one another during coupling despite the pivot movement of the two coupling parts.
