A safety coupling three component parts; a shaped part, a coupling barrel in which the shaped part is rotatably supported, and a plug. The shaped part is a blocking element with a bore that passes diametrically through the cylindrical body. The plug can be inserted through an opening in the housing in a position that varies from the working direction. If the plug is rotated through an angle, the bore moves into a working position and a cylindrical bore in the coupling barrel aligns with the bore in the shaped part. A shoulder area on the plug rests against a stop in the housing and holds the plug in a desired position. |
