The invention relates to an electrode arrangement (1) for applying a transcutaneous electrical stimulus to the surface of a portion of the human ear (2), which comprises a holding element (3) at or in the ear (2) and at least one electrode (4, 5) arranged in or on an electrode support (6). The holding element (3) has a linear guide (7) in which a holding rod (8) is arranged in a linearly displaceable manner in the direction of a longitudinal axis (L) of the holding element (3), wherein the electrode support (6) is arranged on the holding rod (8). In order to improve the handling of the electrode arrangement, the invention provides that latching means (17, 18) are operatively arranged between the linear guide (7) and the holding rod (8) such that the holding rod (8) can be arranged in a latchable manner in predefined relative positions relative to the linear guide (7) and along the longitudinal axis (L), wherein the latching means (17, 18) comprise a rack-shaped contour which is arranged at or on the holding rod (8) and which extends in the direction of the longitudinal axis (L) of the holding element (3).
