1. In a binder ring metal holding hole punched sheets of material, the ring metal including at least one binder ring formed by a pair of binder ring halves, and movable frames to which one end of each ring half is attached for movement of the frames to open and close the binder ring, the improvement comprising:
a ring guard removably installable over the binder ring, when the binder ring is closed, and covering at least a portion of each ring half including a junction where outer ends of the ring halves meet when the binder ring is closed, the ring guard securely gripping the binder ring and preventing a gap from opening between the ring halves when the binder is subjected to a force which would otherwise cause a gap to form between the outer ends of the ring halves and the material stored in the binder to spill out or be damaged; and, the ring guard being comprised of two complementary ring guard halves one of which has a series of posts generally equidistantly spaced about an inner face of the ring guard half and the other ring guard half having a series of holes correspondingly located about its inner face for assembly of the ring guard by installing the posts in the one ring guard half into the holes in the other ring guard half.
