A slide assembly includes an outer slide member, an intermediate slide member, and an inner slide member. The outer slide member includes an opening for mounting a locking member. A lug is mounted on an end of the locking member and abuts against a side of a periphery delimiting the opening. A resilient plate includes a first end fixed on the outer slide member and a second end pressing against the lug of the locking member, thereby biasing the other end of the locking member away from an inner face of the outer slide member. An unlatching member includes an end fixed on the intermediate slide member. The unlatching member further includes a substantially U-shaped actuating section extendable through a slot in the intermediate slide member. Two downwardly extending stops are formed on two lateral sides delimiting the slot by pressing.
