1. An assembly for fastening a retractable antenna to the body of an automotive vehicle, comprising:

  • an antenna casing in the form of a tube;

    an electrically conductive rod slidably inserted and retractable in said casing, said casing being provided with means for facilitating the connection of an electrically conductive cable to said rod; and

    an elastic mounting sleeve provided at one end with an outwardly facing circumferential groove for receiving, flanking and gripping an edge of a preformed hole in said body upon an insertion of said sleeve through said hole during a mounting operation, said sleeve having a substantially spherical inner surface at said one end, said casing having at one end a distended section with a substantially spherical outer surface engaging said inner surface in a pressure fit and hugging said inner surface over a substantial part of the area thereof upon an insertion of said casing into said sleeve during said mounting operation, said spherical surfaces coacting to facilitate an inclination, within limited angles, of said casing and said rod with respect to a surface of said body in a region about said hole, said casing having a substantially cylindrical outer surface and an annular shoulder projecting therefrom and spaced from said spherical outer surface, said sleeve having in an unstressed state a substantially cylindrical wall formed with bellows-like undulations and at an end of said sleeve opposite said groove with an annular bead for gripping said cylindrical outer surface and for engaging said shoulder regardless of the angle of inclination of said casing with respect to a surface of said body in a region about said hole.
