1. A device via which components are pressable onto a heat sink, the components being mounted on a carrier plate, the heat sink being arranged on a side of the carrier plate which, at least in a cooling region, has no components, and heat being dissipatable from the components at least through the carrier plate, the device comprising:
at least one hollow body for accommodating at least one fastening body; and
at least one spring arm shaped as a Greek upper case letter-shaped Omega, an end of the at least one spring arm having a bearing face for transmitting a pressing force (F) to a component to be cooled;
wherein the bearing face at the end of the at least one spring arm is formed as a polygonal flattening; and
wherein the device is formed in one piece as an injection-molded plastic part,
wherein an internal diameter of the hollow body is set such that both the fastening body, and insulation which is attachable to an inner wall of the hollow body and outer wall of the fastening body is accommodated.
