Abstract
Arrangement for holding a tool fitting has a spindle with a forward directed surface and a bore which intersects the forward directed surface and which, starting from such surface, extends rearwardly in order to receive a shaft of the tool fitting. A device for locking the tool fitting with the spindle has an inner and an outer locking element which engage on another. The locking elements act in the manner of a bayonet coupling, wherein a projecting element is disposed in a blind stop groove extending first axially and subsequently radially in a circumferential surface starting from an end face.
