Please see picture attached. Need to know what the noun is for the part circled in red.

Story: keep getting SES 28-32 and 28-83 on my 2004 BMW 330Ci for the past two years. Been cleaning my Gruppe-M A(K&N) filter and MAF on the reqular every oil change (5k miles). Resetting SES everytime with fault code reader. Decided to check the hoses. Tugged a bit on the one circled in Yellow and dang thing broke off pretty easily. My hope is that this is my SES culprit. Please Provide info or DIY assist. Thank you.
