Each male detent member has a miniature flat brick-shaped compartment for a sepentine (particularly U-shaped or S-shaped) flat spring whose front portion extends from the compartment and snaps into the respective female detent member. The male detent member or members are mounted on the detachable component and the female detent member or members are provided in or on the permanently installed component, preferably very close to the gum of the respective jaw. The casing which defines the compartment of the male detent member can be a prefabricated part or it may be formed, at least in part, during casting of the metallic part or parts of the detachable component. The overall dimensions of the male detent member need not exceed 5x3.5x1 mm.</p> |
