The attachment plug comprises a sheet (2) of spring steel, which is bent to form a substantially cylindrical sleeve, said sleeve being provided with lugs (3-6) spaced apart along said sleeve and punched from the metal sheet and bent outwardly at a certain angle. The lugs punched in the sleeve comprise at least two different lengths of lugs (3, 5; 4, 6), said lugs being disposed in the longitudinal direction of the sleeve, one after the other, and comprising short lugs (3; 4) and long lugs (5; 6) in an alternating sequence. Two sets of lugs (3, 5) are bent in a direction outwardly from said sleeve and two sets of lugs (4, 6) are bent in a direction towards the inner portion of said sleeve, each set of lugs comprising at least two different lengths of lugs (3, 5 respectively 4, 6). The ends of the lugs bent outwardly (3, 5) are directed towards the inner end of the sleeve and the ends of the lugs (4, 6) bent inwardly are directed towards the outer end of the sleeve.</p> |
