ABSTRACT:
Disclosed herein is a device for rigidly coupling a handle to its corresponding manual instrument, and an instrument provided with the said device, comprising: a first element that can be connected to a handle, or else be made in one piece therewith, and has a terminal stem, the diameter of which is less, provided with projections whose surfaces, turned towards a shoulder defined by it with respect to the body of the first element, slope both with respect to the axis of the first element and to a plane perpendicular to the said axis; a second element provided internally with an axial hole, which allows the passage of the first element, and a number of projections equal in number or a multiple of those of the said stem, with lower surfaces shaped to accept flush therewith the sloping surfaces of the projections with which the said stem is provided.
The coupling is ensured by a ring nut that can be screwed to the first element and be carried flush up against the upper surface of the body of the instrument to which the second element is fastened, and by a locator member positioned at the side of at least one of the projections on the second element.
