    (54) Adaptor for plugs connected with co-axial cables


    (57) The adaptor for co-axial plugs of the invention presents two metal contact elements (20, 30) included in a base support (40; 62) made of plastic material. The old-type plug is inserted within the transversal space (50) in the connecting element.
    The adaptor has two contact elements, one of them (30) connecting with the earth and presenting at least two partially cylindrical surfaces facing each other (31) and a transversal cylindrical element (33) surrounding and receiving within its interior the external part of the old-type plug, and yet another central contact element (20) receiving and transmitting the signal and presenting a central cylindrical metal part (21) and an appendix in the shape of a fork (23) or of a cylindrical tube (24), so as to establish a sure contact with the central element of the old-type plug.
