Please help me identify the purpose and destination of this hose

Hello good people,
I just finished putting everything back together after a DIY valve cover gasket and crankcase breather cover and hose job on my W202 - a 1999 C280 Sport. A friend was helping me with the work - he took most of it apart while I cleaned the covers and did the sealant, then he left and I reassembled everything. I came across this little hose on the driver side, sticking out the back of the air intake manifold... and I don't know what it is. My buddy doesn't remember moving or removing it, and I can't see any sensible place to insert the loose end in or around the throttle body, the fuel rail or the breather covers. It seems to fit perfectly in the clip shown in the fourth picture, which leaves the end hanging out in empty space. Que? Help me Obi-BenzWorld Kenobi, you're my only hope.
