Abstract
Abstract A novel plastic cage for rolling bearings split at at least one point of its circumference, the abutting faces of the split ends being provided with mutually corresponding projections and depressions to form-lock the ends relative to each other radially and axially and for tangential fixation of the abutting faces of the split ends, one abutting face having integrally formed therewith at least one resilient tongue with a hook projection and the other abutting face being provided with a cooperating recess and a depression for the hooked projection.
