A device for connecting two tool parts having a common axis. The device includes a fitting pin projecting axially from the first tool part and a connecting sleeve projecting from the second tool part and having a mating bore for receiving the fitting pin. A tightening mechanism equipped with a tightening bolt movable in a cross bore of the fitting point assures a sufficient planar surface to planar surface tightening between the two tool parts. Aside from the tightening in direction of the tightening bolt, a clamping of the fitting pin into the mating bore of the connecting sleeve is achieved through suitable measures, the clamping extending transversely with respect to the tightening-bolt direction and resulting in an automatic centering of the tool parts with respect to their common axis and in a reinforcement of the connection transversely with respect to the tightening-bolt axis.

Dispositif permettant de relier deux pièces possédant un axe commun. Le dispositif comprend une goupille d'assemblage faisant saillie radialement à partir de la première pièce de l'outil et un manchon de raccordement faisant saillie de la deuxième pièce de l'outil et comportant un alésage correspondant pour recevoir la goupille d'assemblage. Un mécanisme de serrage muni d'un boulon de serrage mobile dans un alésage transversal dans le point d'assemblage assure un serrage surface plane contre surface plane suffisant entre les pièces de l'outil. A part le serrage en direction du boulon de serrage, le pincement de la goupille d'assemblage dans l'alésage correspondant du manchon de raccordement est réalisé grâce aux mesures appropriées, le serrage qui s'étend transversalement par rapport au sens de serrage du boulon et qui se traduit par le centrage automatique des pièces de l'outil par rapport à leur axe commun et par le renforcement de la connexion transversale par rapport à l'axe de serrage du boulon.
