Abstract (en)

[origin: EP1522635A2] Quick exchange coupling comprises coupling body parts joined together by a hook connection (3) and a wedge lock (4) acting as a counter holder with opposing pressing surfaces. Coupling plates are provided on the working tools and have recesses in one surface. Preferred Features: A counter piece for the wedge lock is formed by a wedge rod (10) which runs across the surfaces of support plates (16). The wedge rod penetrates the support plates and protrudes on the outer sides of the support plates.
