ABSTRACT:
A pre-assembled post lock assembly for loose leaf binders having separable covers which greatly simplifies mounting of the lock to the binder. A plastic sleeve press-fitted within the barrel assembly of the lock holds a spring biased ball carrier member in alignment with the barrel housing such that the locking balls are disposed for coaction with the cam surface of the barrel whether or not the lock assembly is mounted on the binder.
