1. A clamping retainer for fastening a pole, the clamping retainer comprising:
at least two similarly shaped half shells respectively having a straight side and a clamping side in an axial direction,
wherein at least four or eight bores running in an axial direction are provided, uniformly distributed over a compass of the half shell,
wherein a respective straight first clamping face having a first width is arranged on two sides of the half shell lying opposite each other in a radial direction,
wherein, starting from the straight first clamping face, a length of the half shell in the axial direction increases in multiple steps resulting in further straight clamping faces with an increasing width,
wherein a respective first round clamping face having a shape comprising one of a radius, several radiuses, a parabola around its apex, and a hyperbola around its apex is arranged on two sides of the half shell lying opposite each other in a radial direction and offset by an angle about the axial direction relative to the two sides with the straight clamping faces.
