A middle ear prosthesis coupling member is described that includes a transducer coupling element adapted for coupling to a mechanical signal transducer, and an ossicle fastener coupled to the transducer coupling element and adapted for secure attachment to the short process of the incus ossicle of a patient middle ear. The ossicle fastener includes parallel separated first and second fastener clips. Each fastener clip has two opposing bendable legs adapted for forming an interior region for receiving the short process of the incus ossicle and a relieved opening between opposing leg ends displaceably providing access for the incus ossicle to the interior region. The fastener clips securely enclose the short process of the incus ossicle within the interior region. The first fastener clip is adapted for exerting a force to pull the ossicle fastener toward the short process of the incus ossicle. The second fastener clip is adapted for holding the ossicle fastener in place over lateral movement on the short process of the incus ossicle only and without substantially exerting a force to pull the ossicle fastener toward the short process of the incus ossicle.La présente invention concerne un élément d'accouplement de prothèse d'oreille moyenne comprenant un élément d'accouplement de transducteur conçu pour un accouplement à un transducteur de signal mécanique, et un élément de fixation ossiculaire accouplé à l'élément d'accouplement de transducteur et conçu pour assurer une fixation sûre à la branche horizontale de l'osselet d'enclume de l'oreille moyenne d'un patient. L'élément de fixation ossiculaire comprend des première et seconde attaches de fixation parallèles et séparées. Chaque attache de fixation comporte deux pattes pliables opposées pouvant former une région interne permettant de recevoir ladite branche horizontale de l'osselet d'enclume et une ouverture réduite entre des extrémités de pattes opposées, permettant de fournir un accès de l'osselet d'enclume à la r
