An electrical coupling device which can make efficient electrical contact with the electrically conducting part or parts of one or more insulated electrical conductors without the need for baring all the insulation from the conductor or conductors and without the need for actuating with a tool some form of connection member. The coupling device includes a body portion which has an electrically insulating part and electrically conducting means which comprises metallic piercing means. The coupling device also includes a conductor-locating means which has guiding means for guiding the piercing means along a specific path in the locating means when the locating means and the body portion are assembled together in an operative position. While the conductor-locating means and the body portion are moved relative to one another along said specific path during assembly of the two parts, the piercing means is adapted to pierce the insulation of, and make electrical contact with, the electrically conducting part of an insulated electrical conductor in the locating means, and the locating means and the body portion are releasably retained in the operative position, at least when an insulated electrical conductor is located in the locating means. The coupling device is suitable for use in mains voltage systems, for example as an electric plug, ceiling rose or lamp-holder, or in low voltage systems, for example automobile wiring systems.
