We often get customers phoning up to complain that their detachable towbar neck is no longer working correctly and won't re-attach to the car.
The neck is not faulty, it's just that when it was last removed from the car, the release mechanism wasn't turned far enough to 'click' in to the open position. When this happens the neck springs back to it's 'locked' position while it's off the car.
When it's in it's locked position you won't be able to clip it back on to the car. It will first need to be put back to it's unlocked position.
The video above shows you how to do this.
