ABSTRACT:
A coupling for connecting a tool head and a tool holder. The tool head is inserted with an at least partially conical receiving pin into a correspondingly configured receiving bore in the tool holder. Tool head and tool holder are actuated by clamping elements so that a contact collar on the tool head rests against the counterface of the tool holder. The clamping device is composed of a clamping slide which is movable in the longitudinal direction of the tool holder. In the front part of the clamping slide, movable clamping jaws are provided which cooperate with a pin fixedly disposed in the tool holder in such a manner that movement of the clamping slide initiated during insertion of the receiving pin into the receiving bore causes the clamping jaws to be pushed onto the pin and to thus grip behind an annular groove in the blind bore of the tool head, thus causing the tool head to be locked to the tool holder.
