Security system for articles displayed on an elongate rod

A securable article display system having a base on a support and an elongate rod cantilever mounted to the base. A blocking assembly defines a receptacle for a part of the rod and is configured so that with the blocking assembly in the engaged state: a) the blocking assembly cannot be separated from the rod by movement relative to the rod transversely to the length of the rod; and b) the blocking assembly is movable along the length of the rod to block an article suspended from the rod from moving past the rod free end. The rod and blocking assembly interact in a manner whereby the rod binds with the blocking assembly as the blocking assembly moves away from the base towards the free end so as to thereby prevent the blocking assembly from moving past the free end to separate from the rod.
