A ferrule made of a thermoplastic material having a modulus of elasticity of between 5-12 10.sup.2 MPa, is formed with an axial bore. A tapered sleeve extends from a lower portion of the ferrule. The ferrule is located in a press fit about the shaft end with the sleeve mattingly received within the major diameter of the hosel providing an extended cushion and reinforcement at the juncture between the shaft and the hosel.
