Abstract

An arrangement for holding a tool fitting for driven tools has a spindle with a forward directed surface and a bore which intersects the forward directed surface and which, starting from the forward directed surface, extends rearwardly in order to receive a shaft of the tool fitting as well as with a device for locking the tool fitting with the spindle. Inner and an outer locking elements of the arrangement are engage a bayonet coupling and a manacle ring is engaged with the outside of the spindle. The manacle ring also acts directly on the outer locking element and the outer locking element is formed by a projecting element which engages in a blind stop groove in the inner locking element. The stop groove extends first axially and then subsequently radially in a circumferential surface of the tool fitting starting from an end face of the tool fitting.
