Abstract
A locking ring for a castellated nut threadably connected to a bolt having a transversely extending aperture has a diametrically extending section located in the aperture with opposite end portions engageably located in opposing castellations formed on the nut. One of the end portions of the diametrically extending section overlies and springily cooperates with an annular shaped section located about the outer periphery of the castellated formation to lockingly secure the ring to the nut and preclude inadvertent removal. In one form of the invention, an end portion of the arcuately shaped section is folded radially inwardly to cooperatively engage one of the castellations and in another form the diametrically extending portion is centrally bowed so as to engage the inner periphery of the aperture and thereby minimize relative movement between the locking ring and the bolt.
