"verb+っつの" (or "っつーの") in that example is, I think, a colloquial form of "verb+というのにも関わらず+certain omitted part."

Your sentence may be something like
部屋で寝ているというのにも関わらず+（possible omitted part: "Why do you ask?!," "Isn't it obvious?!" or something）

But, seriously, I've never thought that expression was some sort of colloquial form of more "proper" Japanese. I just use it and when I'm to say the same thing in formal language, I'd use a simpler phrase, "verb+います！," i.e., I'd say "さもなければ部屋で寝ています！"

This has the same meaning and conveys pretty much the same connotation apart from the informality.
