The mechanical coupling assembly allows quick and easy clamping of an implement to an arm. The implement carries a bracket which can be received in a coupling member along a given insertion direction. A locking member is rotatably supported on the coupling member and guided transversely to the given insertion direction between an open position, in which said bracket can be freely inserted into the space of the coupling member, and a locked position, in which the bracket is locked to the coupling member. In the locked position, the locking member projects through the bracket. Fewer than three revolutions, preferably only one and one half revolutions suffice to completely lock and unlock the coupling. The coupling assembly has a cam guide on the coupling member and the locking member is formed with a cam groove. The implement, such as an excavator bucket, can be very quickly clamped to the loader arm, in that the arm is first lowered onto the bucket, the attachment bracket is aligned into the coupling member, and the locking member is rotated through about one and one half revolutions.
