Incorrect. That small plastic pipe goes to the nipple on the intake boot. Looking at the boot, the left side goes into the MAF and then bends - goes straight - and bends about 90 degrees to fit over the throttle body. At the second 90 degree bend, just before it is fitted over the throttle body you will see two nipples. The larger one takes a plastic snap on fitting and below it will be a small nipple fitting. The rubber end fits over this hard plastic nipple that comes out of the boot. It may have broken off, but it is located near and below the snap on fitting for the other larger plastic tube. If it broke off you can fashion a repair by finding a suitable plastic or metal pipe and using JB Weld or equivalent. Just look up Range Rover intake boot and you will find a picture for your year and model.
The larger hose that you are incorrectly using that comes off the side of the throttle body takes a hard tube that goes to that fuel purge valve I mentioned in my early post.
