Abstract: A hearing aid includes an identifier for identifying usage of the hearing aid at a correct side on the left ear or the right ear of a wearer. The identifier is constructed as a rotational element having a first feature and a second feature to be respectively set by a rotational movement.

Abstract: A device for inserting a pin into a hearing aid has a gripper embodied in the shape of a cylinder. In an end face the gripper has an aperture by way of which a pin that is to be placed in the hearing aid is picked up. For this purpose the gripper is pressed onto the pin. After the pin has been successfully placed in the hearing aid, pressure is then applied, by squeezing with the hand for example, to the lateral surface of the gripper. This causes a size of the aperture to be changed in the radial direction, as a result of which the pin clasped by the gripper is released. By this means it is advantageously possible to pick up a pin that is to be placed in the hearing aid and install it while making use of only one hand and without recourse to a tool such as a pair of tweezers, for example.
