A fastener including a body and a locking pin is disclosed, The fastener bod y includes an apertured base and conjoined flexible arms extending from the base and defining a passage therebetween. The locking pin is arranged for movement relative to the fastener body along a predetermined path of travel and within the aperture and the passage defined by the flexible arms. The locking pin has a predriven position and an extended driven position. A resilient lock is provided in conjunction with the fastener body and resiliently exten ds into the predetermined path of travel of the pin, when said locking or drive pin is i n the predriven position, thereby inhibiting movement of said locking pin toward said driven position. The lock remains in position to inhibit inadvertent linear shifting of the drivi ng pin until the flexible arms are inserted through an opening in an article with which the fastener i s arranged in operable association. When the flexible arms of the fastener are passed through the opening in the article, the lock is automatically deflected and removed from the path o f travel of and permits the locking pin to be moved toward the driven position.
