Contact insertable in a metallized hole of a printed circuit card containing two ends (1, 2) designed to project on both sides of the card in position of insertion of the contact and to facilitate the electric connection of any devices. The contact includes a median part (3) joining the ends (1, 2) which assures the electrical connection of the contact with the, metallized interior surface of the hole and at the same time its mechanical retention in the hole. The median part (3) comprises a spiral structure of a rectangular section, the verticles of which define the edges (4) of that spiral structure.
