Abstract
Abstract Electrical contact element designed to produce an electrical connection by interacting with a male element and including means for its connection to an electric circuit at one end while the other end is bent to form a channel with a base side, a top side opposite the base side, and an elastic strap which functions in gripping the male element, wherein the elastic strap has a first portion applied against the base side and prolonged by an inclined second portion which is bent in the shape of a hairpin and prolonged by a portion which extends towards the free end of the channel and towards the base side in such a way as to bear against a point on the top side.
