Tracy,
If you have access to the 'Screwfix' catalogue if not look on their website in the plumbing section and you find something called a tap connector which is a 3/4 inch size fitting with a piece of copper pipe, the copper pipe would shove into your hose pipe and a jubilee clip would secure it and the 3/4 inch fitting would screw to your tap, if you contact 'Screwfix' now you would have it by tomorrow morning :)
