coolant leak underneath

Hi, I'm hoping to get some quick advice to help a friend on his older Prelude (maybe late 80's) leaking coolant. we rolled it onto ramps & could see underneath in middle back of engine a smaller hose juncture that is fastened straight up to the engine that is dripping. The left hose seems to be coming from top & the right of the juncture going straight right. They seem to be the type of snap in hose fasteners you would see on a heater core hose going into a manifold. I don't see much else going on there except for 2 hoses being connected & fastened to the engine. Sorry for the vague descrip but I only could get a quick look. Thanks for any help.
