Quick-action attachment for working implements comprising a first coupling part (2) disclosed on the working implement or, for example, the operating arm of a working machine and having at least one pair of parallel, undercut, mutually facing surfaces (7), and comprising a second coupling part (4) disclosed on the working machine or the working implement and having a pair of parallel, bevelled, mutually in opposite directions facing surfaces (13, 20) adapted to be introduced into engagement with the undercut surfaces of the first coupling part. According to the invention the second coupling part (4) has a first, stationary, bevelled surface (13) and a second bevelled surface (20) which is shiftable between a first position in which the second coupling (4) substantially transversely in relation to the extension of the bevelled surfaces is insertable into engagement with the first coupling part (2), and a second, extended position in which the bevelled surfaces (13, 20) have come into firm abutment against the corresponding undercut surfaces (7) of the first coupling (2) for locking the working implement in attached position. |
