1. A prosthesis socket for receiving an amputation stump of an extremity, comprising:

  • at least one shell with a curved, open cross section and ends which at least partially overlap each other in an applied state;

    at least one tensioning means arranged on the at least one shell, the at least one tensioning means being configured to act in a circumferential direction to tension the ends of the at least one shell relative to each other; and

    at least one connector associated with the at least one shell for connecting a distal prosthesis device,wherein the at least one shell is made from a dimensionally stable plastic with areas of different elasticity, andwherein an inner face of the at least one shell has a direction-dependent surface configuration that offers greater resistance to sliding counter to a direction of insertion of the amputation stump than sliding in the direction of insertion, wherein the direction of insertion is in a direction from a proximal edge of the at least one shell toward a distal edge of the at least one shell.
