I will get a picture.... yes coupler....I kind of make up my own vocabulary, lol. It got broke because my kid was trying to reconnect it after it became "un-coupled?", I want to say unhitched (in Arkansas where I am from, that means divorced.) Long story short, she ended up dropping it and it broke when it hit the floor. Strangely the candy was fine.... note to self, don't eat that candy. I would love to find something that pretty much permanently coupled the cars.
