A contact adapted to be used in conjunction with an electric wire prearranged with a tip connection terminal, of essentially rigid type, and including reception means of the terminal for at least one prevailing part of the length of the same in a direction of insertion (A), electric interface means between tip and contact, against which the terminal is in use abuttingly withheld, and elastic locking means prearranged between the reception means and the electric interface means so as to press in use with predetermined pressure the terminal against the electric interface means and at the same time cooperate with the terminal forming a first angle with the direction of insertion so as to prevent by seizing the extraction of the terminal from the reception means in the direction of insertion; wherein the elastic means and the reception means are shaped so as to allow a user to displace the terminal, against the bias of the elastic means, obliquely with respect to the interface means and to the direction of insertion (A), so as to determine between the elastic means and the terminal a second angle which does not allow the removal of the tip from the reception means along a direction of extraction (B) different from that of insertion (A).
