Abstract: The present invention relates to a power connection device (1) which includes, on the one hand, a female part (2) with a lyre-shaped profile contained within and secured by an insulating support (3), which assembly is fixed inside a panel and is only accessible from one side, and on the other hand, a male part (6) to be plugged into said female part through said accessible side. This device is remarkable in that, in order to transfer high-intensity currents, the female part is composed of a thick, rigid multiclip (2) into which the male part, composed of a single thick plate (6), is inserted during the connection, which female part has a clamping zone (P) and which male part has a thickness (W) such that the insertion force is between 1.5 and 5 daN and that the resultant of the contact resistances is less than 60 N.OMEGA..
