Hi guys, I have a broken purge valve. While testing it, being unfamiliar with the clip on the vacuum line from it, I broke the clip on the hose.

It looks like the blue clip in this picture: https://bit.ly/2u5tvpn

What kind of clip is this? How is it supposed to be disconnected (without breaking it lol)? Where can I find a replacement?

EDIT: Looks exactly like the gray clip in this picture: https://bit.ly/2u6g0pk
