Abstract
A fan guard comprising front and rear portions each including a plurality of radially extending wires circumferentially spaced supporting a plurality of concentrically mounted wire rings. Some of the radially extending wires include an end having a homogeneously extending tab formed thereon. The tabs have a front and back side and are formed by bending the end of the wires into a P-shaped loop defining a slot having parallel edges. The tabs are offset with respect to the portion's joining plane so when the guard portions are assembled the front side of the tabs of the front portion engage the back side of the tabs of the rear portion to form abutments with each other in an interlocked relation preventing axial separation of the guard portions and the loops align to receive a bolt upon which a nut is threaded to secure the guard portions together.
