A snap ring having improved retention characteristics is configured for use inside a cylindrical cavity. The cavity includes a retention device having a retention surface forming an obtuse angle with the cavity wall. As an axial load is applied to the snap ring, it moves along the retention surface, thereby experiencing a reduction in diameter. The snap ring includes a circumferential discontinuity defined by two generally radial planar surfaces, or ring ends. The discontinuity is configured such that the ring ends will abut one another before the snap ring diameter is reduced beyond the retaining diameter.
