This is the bit that goes onto the tap. After continual plugging & unplugging they tend to split & therefore leak

This is the bit that goes onto the end of the hosepipe & plugs into the bit above. Again after continual use they can develop cracks & leak

This is a very useful bit for joining two hoses together. Where I have hopepipes feeding the troughs in the paddocks, the hosepipes themselves can spring leaks after a while. Instead of replacing the whole hose I can cut out the damaged section & join the two parts together with one of these
