A locking device intended as a fastening element for prostheses, of the kind in which the prosthesis is to be attached to a cylindrical member such as a pin (12) or the like. Said locking device comprises a housing (15) with a through opening (16) for receiving said pin (12) and a locking mechanism (18) arranged therein for locking to the pin (12) in one axial direction thereof. In the housing (15) along the opening (16) opposite the locking mechanism (18) there is further arranged a gripping member (19) in the form of a spring- loaded gripping washer with a through opening which is somewhat larger than the diameter of the pin (12) and which by means of actuating means (22, 23, 24) can be brought to an inclined position and grip the pin and by that pull this further into the housing.
L'invention concerne un dispositif de verrouillage pour la fixation d'une prothèse, du type à fixation sur un élément cylindrique, par exemple tige (12) ou autre, qui comprend un boîtier (15) doté d'une ouverture traversante (16) permettant de recevoir la tige (12) et à l'intérieur d'un mécanisme de verrouillage (18) pour le verrouillage de la tige (12) selon une direction axiale de celle-ci. Dans le boîtier (15) le long de l'ouverture (16) à l'opposé du mécanisme de verrouillage (18) se trouve également un élément de blocage (19) sous la forme d'une rondelle de blocage à ressort dotée d'une ouverture traversante dont le diamètre est quelque peu supérieur à celui de la tige (12) et qui, par un mécanisme d'activation (22, 23, 24), peut être amenée dans une position inclinée et bloquer la tige, c'est-à-dire la tirer en peu plus en avant dans le boîtier.
