How To add “( )” around a text field in a formlas of airtable

[NICK75]

I already have a formulas that work fine although i need to add “( )” around my Base field called MODELE

IF(AND({PRODUIT},{MODELE}),

{PRODUIT} & " - " & {MODELE} & "\n",

IF({PRODUIT}, " " & {PRODUIT} & "\n") &

IF({MODELE}, " " & {MODELE} & "\n"))&

Right now when I got the formulas it shows 

ANNEAU DE FOULARD - ALEXANDER

I would like to add ", so it will show this.

ANNEAU DE FOULARD - "ALEXANDER"
