Patent number: 9500438Abstract: A lockable snap-clip fastener (10) has two spring-biased jaw members (12, 14) and a slidable locking bar (16). The same spring (13) that biases the jaws (12, 14) holds the locking bar (16) in either an open or a closed position with one of its arms. Since the bar (16) is held in either the locked or unlocked position, it is more secure and must be positively actuated in order to transition from one configuration to the other.Type: GrantFiled: September 7, 2012Date of Patent: November 22, 2016Assignee: MAGPUL INDUSTRIES CORP.Inventors: Michael Mayberry, Brad Bennett
