Is this brake line coupling...ok?

I came across this brake line coupling (?) that connects a hose to a hard line near the driver's side FCAB. I only ask about it because I thought I heard a hydraulic related noise when tightening a motor mount bolt and when I looked for the source this hose coupling caught my eye. I can slide the hose's metal coupling onto the hard line more, but it will return to the original position if I let go and if I push in the black plastic ring it will pop back out. Is this freedom of movement normal? Hopefully this isn't a completely silly question - I searched for a bit but I might've missed something.

Is it possible/likely that brushing up against this could allow air into the brake line? A noise made me look at it initially and I wasn't sure if the noise was the sound of the mechanism sliding or a hydraulic seal breech.

EDIT: nm, I'm gonna bleed the whole brake system- I don't think it'd have made a noise I'd notice without some air going in, plus I'm already on jackstands and it's about time for a flush anyway

Nope, unless it leaking then its air tight..
