Abstract

Device for locking a male element such as a shaft engaging in the bore of a female element such as a wheel hub against axial displacement. An annular groove is provided in the bore of the female member and has a first annular surface engageable by an elastically deformable locking ring mounted on a reduced section of the shaft member. A displaceable member such as a nut is moveable relative to the shaft member and has a second surface engageable with the locking ring. At least one of the surfaces is tapered so that upon movement of the surfaces toward one another, the locking ring is displaced radially outwardly to engage in the groove and lock the elements together.
