Abstract: The contact clip according to the invention comprises a contact portion (11) comprising two elastic blades (15) capable of pressing a male contact portion (2) against an interior cylindrical portion (110) of the said contact portion. In view of the elongate shape of this contact portion, electrical contact between the contact clip and the male contact piece portion is had over a large surface area, thus reducing the contact resistance and the heating when high currents are passed. The contact clip further comprises an attachment portion (10) and possibly an end portion (12) and is intended to be fitted inside a hollow housing of a female contact piece (3).
