Body (1) of the tapping attachment incorporates a small pin (7), in correspondence with one of the ends of the conventional slit (4) for the temporary coupling of a guillotine (6) which seals the attachment during the removal of the perforator drill and until final implantation of the branch, which pin acts as a hinge pin for the guillotine (6), the latter incorporating on one of its ends a small bent protrusion (9) in the form of a hook for its hinged union to pin (7), and on the opposite end has a handle (10) for use in a swivel operation, with a leveraged action which makes the sealing operation simpler, faster and requiring less effort. In addition body (1) of the tapping attachment is provided with a gasket meant to be mounted on it coaxially and externally, which seals said slit (4) after removing guillotine (6), and which is embodied as a plastic material ring with a certain capacity of deformation. <IMAGE> |
