A quick unlocking optical fiber plug connector has a casing, an optical fiber plug module, a pull lever and a cable assembly. The optical fiber plug module is mounted on a front end of the casing and has a module case and an optical fiber shaft assembly. The module case has a locking arm, a resilient linking tab and a connecting member formed on the module case and connected to one another. The pull lever has a drive member formed on a front end of a lever body. The drive member has a connecting slot and a through slot to accommodate the connecting member and part of the resilient linking tab. The drive member and the connecting member are securely connected to prevent the pull lever from being inadvertently disengaged from the resilient linking tab. The pull lever is straight and strap-like to facilitate pulling action for unlocking.
