water leak

[vrlpg]

Hi there guys, first up i'm not very mechanically savvy you'll have to excuse any mistakes in my description.

my daily is a 94' VR commodore, i have a leak that was coming from just above the water pump at first we thought it was coming from the water pump but after lifting the alternator and getting a better look realised it wasn't the water pump.

the leak was coming from a plastic double ended connection that connects a hose thats starts from the top of the water pump and goes to just below the thermostat.

please find the pictures attached guys. The pictures are of the hole that the double ended plastic connection fits into and joins up with the hose, 2nd photo of the hose and of the connection which was rotted and pretty much crumbled in my hands.

My main question, what is this double ended connection called? Can i get one aftermarket, commercially etc, and when going to my local Peps, Bursons or super cheap is there any specific information that i would need to give them.

Thanks!
