Pin and retainer locking system

A pinned connection assembly comprising:

• a first rigging component having an end with at least one coupling aperture;
• a second rigging component having an end with at least one coupling aperture;
• a rigging pin inserted through the coupling apertures of the first and second rigging components, the rigging pin having an end with at least one multi-directional locking groove;
• and
• a lock having a moveable end, a key for engaging the multi-directional locking groove of the rigging pin, and a spring member compressed between the key and moveable end.

A method of assembling a pinned connection assembly comprising first and second rigging components each having coupling apertures, the first rigging component having a retention aperture transverse to the coupling aperture, a rigging pin having a retention groove, a locking pin having a multi-directional locking groove, and a lock having a spring member and a key, the method comprising:

• inserting the rigging pin through the coupling apertures of the first and second rigging components;
• inserting the locking pin through the retention aperture of the first rigging component and the retention groove of the rigging pin;
• placing the lock on the locking pin so that the key is received in the multi-directional locking groove;
• compressing the lock against the locking pin to compress the spring member of the lock and move the key within the multi-directional locking groove;
• rotating the lock to move the key within the multi-directional locking groove;
• and
• releasing the lock to lock the key within the multi-directional locking groove.
