Abstract

A wear display (5) is provided between the ball coupling arresting lever (2) and the housing (1). The display shows the position the lever should take up in the safe locking position, and consists of a pointer (6) which may be a notch or a raised part. An extension (4) fitted to the arresting lever pivot bolt (3) and screwed to the coupling housing (1) has a multi-coloured scale (7). The pointer (6) moves along the scale when the arresting lever is moved.
