ABSTRACT:
An insulation-piercing connection arrangement for an electric wire in which an auxiliary insertion part (4) is displaced by a removable shank (5) acting as a lever in order to apply the necessary pressure for slicing through the insulating covering (20) of an electric wire (2) to be connected, and to insert the core (21) of said wire in a slit. The auxiliary insertion part (4) has a shank-receiving duct passing therethrough and includes a pusher (40) for pressing against the wire to be connected, it also includes a guide device (43) including wheels which co-operate with guide grooves (73) provided in the housing (7) containing the connection arrangement in order to enable the auxiliary insertion part (4) to perform pseudocircular insertion motion, thereby accelerating the tilting thereof when it is displaced between its two extreme positions.
