Plastic safety ring which you attach to the metal ring where you tie your horse and slip the lead rope through. If your horse was to panic the device releases the horse and is then re-usable. Although it cannot prevent injury in all cases it does significantly reduce the risk. This must-have piece of safety kit is safer than string and has now been made even better and more versatile with a new security sleeve. They can be used inside and outside the stable as well as whilst travelling in a horsebox or trailer and can be safely left outside in all weathers.
