Yes...I think you see the light. Trim off just a little bit from the tip that connects directly to the battery's vent hole...and it should extend over to the car's vent tube without being pinched between the battery and the air vent/grill (in the battery compartment):

The pic below is my set-up in the you can trimmed vent tube is not squished in the pic...I used a pair of scissors & cut off approx 1/8" after measuring twice (cut once). I laid the tube along the path over to the gray vent tube to see how much of the tip needed to be cut off to bring the extending section closer to the battery and to prevent it from being squished up against the vent/grid that is directly behind the elbow section of the extending vent tube.

versus yours (which is slightly pinched) in the pic below (and where you've nicely circled the area in white to highlight the location)

Just an FYI...this pic below (that you circled) is Jamie (Jamesdc4) from BimmerForums...that image is taken from his great battery replacement DIY on that forum. And I think that his vent tube isn't "pinched" in the image because the battery isn't really set in place yet. His cables aren't attached and the battery hasn't been pushed all the way back up into the corner yet:
