A cable connector includes a body having a longitudinal axis, an inner post, an outer barrel mounted to the inner post, and a fitting mounted to the inner post. The inner post includes a front, a rear, and an outwardly-directed front flange at the front. The fitting includes a front, a rear, and an inwardly-directed rear flange at the rear. The fitting is mounted on the inner post so that the front and rear flanges overlap to define a toroidal volume. A wave washer and a lock washer are each carried in the toroidal volume. When the fitting is applied to a female post, the wave washer and the lock washer are compressed between the front and rear flanges and exert an axial bias on the front and rear flanges to prevent axial separation of the fitting and the female post.
