What is the ruling on purchasing a car from an Islamic bank if the contract includes a clause prohibiting the sale of the car until all installments have been paid, even if it is said that this clause does not apply to the employee?

The stated condition, which is mortgaging the car for its price in favor of the bank until the price is fully paid, is permissible and valid according to the most preponderant opinion, and this is the view adopted by the Islamic Fiqh Academy. There is no objection to the bank stipulating this condition. However, if the verbal agreement was to the contrary, then it holds no weight. The important thing is the availability of Sharia-compliant controls in the transaction itself, such as the bank owning the car and it entering its possession and guarantee before selling it to you, if the transaction is a murabaha or installment sale.
