You can't say "Non ho detto quel".
When quello is used as a pronoun, only the form quello is possible. When it is used as an adjective, you must follow the same rule used for the articles il/lo. Il -> quel / lo -> quello.
Examples:
prendi quello straccio (lo straccio)
prendi quel gatto (il gatto)
guarda quell'uomo (l'uomo)
guarda quello
The same rule applies to the plural form quei/quegli.
