special usages of to iu??

[Dante12]

こぎれいではあるがだんらんのない家庭という檻の中に 、つながれているという思いがつのった。

Can anyone here pls explain to me the usages of to iu here?? to iu in this sentence doesnt seem to make any sense to me.....because from what i know to iu is a quote marker...but the usages of to iu here is a bit diff from the usual quote marker...
So if anyone knows here, can u pls explain it to me?? I will really appreciate any help available....

and does kogirei dewa aru means having a nice home??

THANK YOU!!!

Kogirei means neat, shipshape, clean, etc.
Danran is often used to describe a family, that is happy.
So "kogirei dewaaru ga danran no nai katei" means the home is well-kept, nicely clean but it lacks in family hapiness.　
The speaker compares that home to a cage.

〜という思い : a feeling/thought that is.....
〜という檻 : a cage that is.....

To iu here indicate that its preceding clause explains the noun that follows.

The speaker has a feeling that he is chained in a cage which is a home which is nice and clean but without hapiness. and the feeling is growing/mounting inside himself.

≪【こぎれいではあるがだんらんのない家庭】という【 檻】の中に 、つながれている≫という≪思い≫がつのった。

Ermmm...I sincerely apologized for this but it seems that I forgot to include the qns of the usage of de as in こぎれいではあるが.

I cant seem to understand the usage of de here that follows kogirei...

[KrazyKat]

Its from である＝だ（です）　the は　 there is contrastive.
