The permanent percutaneous electric connection device (100) comprises a percutaneous catch (110) adapted to be connected to an external entity of a body of a patient, an electric connection body (120) adapted to be coupled with an internal entity (150) of the body of the patient, a set of intermediate connection intended to be arranged between the electric connection body and the internal entity and adapted to be fixed in the body of the patient, and an electric cable removably connected to the electric connection body and to the intermediate connection. The permanent percutaneous electric connection device (100) comprises a percutaneous catch (110) adapted to be connected to an external entity of a body of a patient, an electric connection body (120) adapted to be coupled with an internal entity (150) of the body of the patient, a set of intermediate connection intended to be arranged between the electric connection body and the internal entity and adapted to be fixed in the body of the patient, and an electric cable removably connected to the electric connection body and to the intermediate connection. The percutaneous catch and the electric connection body are connected with each other through a connection body, and are designed for a partial osseous burying in the osseous structure. The connection body is designed for a total osseous burying in the osseous structure. The percutaneous catch includes a percutaneous pillar (111) arranged on an anchoring base, where the pillar includes a connection. The electric connection body includes a connector arranged on a base, where the connector is intended to be coupled with the internal entity. The connection body, the base of the percutaneous catch and the base of the electric connection body are configured for the total osseous burying in the osseous structure so that the percutaneous pillar and the connector cover a surface of the osseous structure. The percutaneous catch and the electric connection body: are separated
