You can just use your jubilee clips to hold the hoses on the inlet/outlet of the wort chiller but if you want quick conect/disconnect:
At the wort chiller end of things you will need 2 x male hozelock connectors (B&Q blue are fine) attached to the couplers plus 2 x female hozelock connectors on your hoses (again B&Q blue are fine).
Then you need whatever you need for the water supply tap end, either in your kitchen or for the outside tap.
Thanks for spelling this out for me! Much appreciated.
