An electrical connector comprises a housing, a plurality of contacts arranged in the housing, an actuator mounted on the housing, capable of rotating with reference to the housing and a pair of fixing tabs positioned in the vicinity of two ends of the actuator. Each fixing tab has a lock portion for engaging with a flexible printed circuited connected to the electrical connector and a spring portion connected to the lock portion. The fixing tab is engaged with the actuator so that rotation of the actuator from an original position to a release position causes the lock portion of the fixing tab to disengage with the flexible printed circuit connected to the electrical connector and the actuator resumes from the release position to the original position under a resilient force exerted thereon by the spring portion of the fixing tab.
