[Closed] what's this part called (car washer hose content)

Rather typically, fixing a small problem has created a slightly larger one. In removing the washer pump I've managed to crack this connector so when refitted it leaks the contents of the reservoir onto the driveway.

1st problem is the connector doesn't want to pull free from the flexible pipe - I don't want to break it so is it just a case of applying sufficient force or is there a special technique? And 2nd, what's this part called?? (Windscreen washer hose connector just brings up male\male couplers)
Its a Vauxhall zafira FWIW
