Abstract
A working machine includes a lift arm and an implement coupling fixed to the lift arm. The implement coupling includes a locking element which is displaceable between an inoperative position and an operative position in which it is designed to shoot into a hole in the implement in order to lock the implement to the implement coupling. The locking element, over a first section of its length, has a first cross-section that will allow the first section of the locking element to be shot into the hole in the implement, and over a second section, which adjoins the first section, has a second cross-section which prevents the second section being shot further into said hole. The second section comprises a stop face designed to be brought to bear against the implement when securing the implement to the implement coupling.
