Zipper device comprising an electrically conductive slider

A monitor device for monitoring a zip closure system, said monitor device comprising:

• a first tape and a second tape, each provided with a series of members, that can be coupled and uncoupled with the series of corresponding members;
• and
• a conductive slider made of electrically conductive material, the conductive slider being arranged with the series of members in such a manner as to enable the members of the two series to be coupled together by moving in one direction along said series of members and to enable them to be uncoupled by moving in the opposite direction;
• wherein said monitor device further comprises:
• at least first and second conductive strips of electrically conductive material, that are secured to the first tape and that are arranged transversely relative to the longitudinal axis of the first tape, said first and second conductive strips and the conductive slider being configured in such a manner that the first and second conductive strips are electrically connected together by the conductive slider when said conductive slider is moved to be level with said first and second conductive strips;
• and
• a detector-and-signaling system configured to detect the state of electrical continuity between the first and second conductive strips.
