The present invention provides a fixing device for receiving and attaching operating elements to the faceplate of hearing devices or hearing aids, whereas the operating elements comprising connectors for the electrical connection to further electric or electronic components of the hearing device or hearing aid, further comprising a bush having a slot continuously extending from one end to the other end of said bush. Such a bush may on one hand be shifted from the outside onto a defined area of the operating element and on the other hand be inserted into an opening of the faceplate with an opening diameter dimensioned according the outer diameter of the bush. The clamping effect thus acts both onto the bush and the operating element, thereby fixing reliable both the bush and the operating element within the faceplate. The bush or the operating element respectively may thus easily non-destructively be removed from the faceplate by pulling it out of the opening in the faceplate.
