How to replace drain hose?

Hi
Can someone help,detergent tube on my zanussi fj1093 came away from the drum causing quite a flood,and in a blind panic cut the drain hose so as to get the machine out far enough which now leaves me with another problem,can it be coupled together or should it be replaced and how easy is it to refit the detergent tube seems quite akward.HELP
