washer bottle pipe leaking bulkhead connector still

HI just had the pipe connector popping off at the bulkhead read this great forum and found the pipe which was unclipped completely popped off,

i reconnected the connector but is still leaking bad , how hard do you have to push this in it seems to be clipped in ok but still leaking very bad.i read somewhere it might not be pushed in enough and try washing up liquid ?

Also when its unclipped it doesnt seem to be leaking anywhere top and bottom of the connector,but when reclipped and rear washer used it leaks out from top and bottom of connector , do i have to buy a new connector ? cut pipe and refit and can you buy these connectors ? oh i got two left hands lol
