ABSTRACT:
The metal sleeve which is formed with the slot along a generatrix, comprises zones of relatively large wall thickness (D) and zones of relatively reduced wall thickness (d) in alternative relationship around the periphery. The zones of reduced wall thickness are in the form of annular sectors of finite length having parallel walls and radiused transitions into zones of relatively large wall thickness (D). When an insert is pressed in, the sleeve is expanded very uniformly over the entire periphery.
