  • Patent number: 4685176
    Abstract: A safety fastener for lugs includes two bolts pivotally mounted to a block in a cylindrical hollow body. The bolts can move between a lug-engaging latching disposition and a lug-releasing unlatching disposition, and are biased to the latching disposition by springs. A carrier disc is rotatable between a locking disposition and a release disposition to rotate a bolt-blocking member from a retracted disposition to a bolt-obstructing disposition. When the member is in its retracted disposition it allows the bolts to be displaced out of their latching disposition to accept the lugs. When the member is in its bolt-obstructing disposition it prevents this displacement of the bolts, and therefore prevents engagement of the lugs.A yoke is pivotable on the carrier from a rest disposition to a displacement disposition protruding from the carrier only when the carrier is in its release disposition.
