A coupling assembly (1) for attachment of an implement (49) to an excavator. The assembly comprises a pair of load transmitting plates (2, 3) with a transverse plate (4) welded thereto. The load transmitting plates (2, 3) have recesses (15, 16) on one end to enable connection to a pin (17) of the implement and rotatable hooking elements (11, 12) at the other end to enable connection to pin (13) of the implement. A clevis (8) is located in transverse plate (4) to permit rotation of the hooking elements (11, 12) into and out of fixed contact with the pin (13) when a handle (50) is rotated.

L'invention concerne un ensemble de couplage (1) servant à fixer un outil (49) à un excavateur. L'ensemble comprend deux plaques de transmission de charge (2, 3) soudées à une plaque transversale (4). Les plaques de transmission de charge (2, 3) présentent, à une extrémité, des évidements (15, 16) permettant un raccordement avec une tige (17) de l'outil et, à l'autre extrémité, des éléments d'accrochage rotatifs (11, 12) permettant un raccordement avec une autre tige (13) de l'outil. Une chape (8) est disposée dans la plaque transversale (4) et permet aux éléments d'accrochage (11, 12) de tourner pour assurer un contact fixe avec la tige (13) ou s'en désolidariser, lorsqu'une poignée (50) est tournée.
