Semi-trailer coupling with a coupling plate (2), containing a feeder opening (4) for a connector pin to a semi-trailer. A coupling claw (12) is manoeuvred by the connector pin at the beginning of the connecting process, and is guidable between a coupling site, in which it holds the connector pin in the feeder opening and a position, in which the connector pin is released. By means of a control device (32, 34, 42) a lock unit (26) is manoeuvrable from a locked position, in which it locks the coupling claw (12) in its' coupled position, to a position, in which the coupling claw is released and the locking element is hooked. The control device (32, 34, 42) is comprised of a control handle (32), and a locking device (70, 72, 74) designed for locking the control device, when the locking element is in locked position. According to the invention there is a security device against unintentional release of the locking device (26) from the locked position when not connected or if the locking device is faulty (70, 72, 74), it is designed to be connected as a function of the locking device's (26) assuming the locked position.<IMAGE> |
