A middle ear prosthesis coupling member comprising: 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 (310, 410) of the incus ossicle (309, 409) of a patient middle ear, characterized in that the ossicle fastener includes parallel separated first and second fastener clips (205a, 205b), each fastener clip having: two opposing bendable legs (206a, 206b) forming an interior region (207a, 207b) for receiving the short process of the incus ossicle, and a relieved opening (208a, 208b) between opposing leg ends displaceably providing access for the incus ossicle to the interior region, so that the fastener clips securely enclose the short process of the incus ossicle within the interior region; wherein the first fastener clip is adapted for exerting a force to pull the ossicle fastener toward the short process of the incus ossicle; and wherein the second fastener clip is adapted for holding the ossicle fastener in place over lateral movement on the short process of the incus ossicle and without substantially exerting a force to pull the ossicle fastener toward the short process of the incus ossicle; whereby vibration generated by the mechanical signal transducer is coupled by the prosthesis coupling member to the short process of the incus. 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 (310, 410) of the incus ossicle (309, 409) of a patient middle ear, characterized in that the ossicle fastener includes parallel separated first and second fastener clips (205a, 205b), each fastener clip having: two opposing bendable legs (206a, 206b) forming an interior region (207a, 207b) for receiving the short process of the incus ossicle, and a relieved opening (208a, 208b) between opposing leg ends displaceably providing access for the incus ossicle to the interior region, so that the fastener clips securely enclose the short process of the incus ossicle within the interior region; wherein the first fastener clip is adapted for exerting a force to pull the ossicle fastener toward the short process of the incus ossicle; and wherein the second fastener clip is adapted for holding the ossicle fastener in place over lateral movement on the short process of the incus ossicle and without substantially exerting a force to pull the ossicle fastener toward the short process of the incus ossicle; whereby vibration generated by the mechanical signal transducer is coupled by the prosthesis coupling member to the short process of the incus. two opposing bendable legs (206a, 206b) forming an interior region (207a, 207b) for receiving the short process of the incus ossicle, and a relieved opening (208a, 208b) between opposing leg ends displaceably providing access for the incus ossicle to the interior region, so that the fastener clips securely enclose the short process of the incus ossicle within the interior region; wherein the first fastener clip is adapted for exerting a force to pull the ossicle fastener toward the short process of the incus ossicle; and wherein the second fastener clip is adapted for holding the ossicle fastener in place over lateral movement on the short process of the incus ossicle and without substantially exerting a force to pull the ossicle fastener toward the short process of the incus ossicle; whereby vibration generated by the mechanical signal transducer is coupled by the prosthesis coupling member to the short process of the incus.
