multiple stream coming out of sprout instead of single

multiple stream coming out of sprout instead of single

a silicon or rubber tubing about 1/4 inch came off the Keurig coffee maker and I don't know where it came from. Now, the coffee comes off in double or triple stream instead of single stream. I speculate the little tubing has some thing to do with altered stream. I would like a diagram to show where and how this tubing be reattached.
