 derart auch ein Ausspringen der Sicherheitskuppel beim Reissen der Hauptkupplung wirksam verhindert. 



   Um den Sicherheitskupplungshaken zu öffnen und dem   Bügel 10   seine normale Drehbarkeit wieder zu geben, wird der Drehzapfen 11 in der Pfeilrichtung (Fig, 2) in die mit gestrichelten Linien angedeutete Stellung gedrückt, wodurch der   Kupplungsteil is   des Zapfens die Bohrung im Haken verlässt und dadurch dem Drehen des Bügels keinen Widerstand entgegensetzt.

 EMI2.1
 in this way, the safety dome also effectively prevents the safety dome from jumping out when the main coupling breaks.



   To open the safety coupling hook and to give the bracket 10 its normal rotatability again, the pivot pin 11 is pressed in the direction of the arrow (Fig, 2) into the position indicated by dashed lines, whereby the coupling part is of the pin leaves the hole in the hook and thereby does not offer any resistance to turning the bracket.



   PATENT CLAIMS:
1. Device to prevent the safety coupling from loosening if it breaks
 EMI2.2
 Rotary bolt (2) is arranged to close the same when the coupling eye is inserted, which is secured in its closed position by resiliently snapping into the tip of the hook.

Claims

2. Device according to claim l, in which the bracket arranged on the safety coupling hook forms the rotary bolt, characterized in that the bracket (10) through a non-circular point (13) of its displaceable pivot pin held in its operative position by a spring (14) ( 11) is found in its closed position, but can be rotated after partially pulling out the pivot.
