The device includes an insulating casing defining at least one connecting housing and, in each connecting housing, an interconnection piece arranged in the casing and provided with at least one connecting branch, a connecting spring, a cam for compressing the spring to uncover the connection opening, and to allow the conductor for connecting to be introduced. The cam which is fitted into the connecting housing so as to be able to move in terms of rotation between a start of travel corresponding to the spring being in a relaxed state and an end of travel corresponding to the spring being in a compressed state, and which is provided with an operating lever extending at least partially out of the casing to allow the cam to be operated between the start and the end of travel and which has a cam path includes on the one hand, a zone known as the dead zone, through which the cam can pivot from the start of travel without acting on the spring and, on the other hand, a zone known as the active zone, following on from the dead zone. The device also includes rib and stalks slowing the rotation of the cam in the start-of-travel and end-of-travel position.
