I recently bought a new garden hose. The hose seems to connect snugly to the existing fitting on the tap, but it leaks a bit and as soon as the water pressure in the hose goes above a trickle, it pops off. Any idea what's wrong or how to fix it?
Note that the loose plastic sleeve in the 2nd picture doesn't go all the way up, but as far as I can tell it's not meant to provide a seal anyway. Also, I have no idea what either side of the hose/fitting are called, which makes searching the Internets a bit difficult.

A hasty assessment: it is probably because it's a piece of junk. Give it back. I could blame pilot error: you are supposed to push it on until it clicks at which point it's locked on. You are probably not pushing hard enough. But the entire point of click-lock fittings is to be easy and foolproof. If the thing is amenable to having you THINK it's on, but it isn't locked, then it is definitively junk, failing to provide the one thing that distinguishes it from an ordinary screw-on hose. Alternatively, it may be a total piece of junk where you are in fact locking it but the cheap plastic parts are incapable of holding under normal water pressure. Either way, give it back.
Here, for comparison, are fittings that are increasingly better quality than yours. A reasonable all-plastic one, a "metal where it counts" one, and an all-metal one. Any of these would be fine. In your example, the bib adapter looks so flimsy it's bound to crack and fall off the spout within a week if you ever get it to actually hold.
