Abstract: The fastening device comprises a housing having a joint for connecting to the link, and two coaxial pins for joining it to the object, of which at least one is mounted in a manner that enables it to slide between two positions, one being retracted from the wall of the housing and the other projecting from the wall of the housing for engaging inside an opening of the object, coaxial to a second opening for accommodating the other of these pins. The fastening device also comprises an elastic device for attempting to constantly hold the sliding pin in the retracted position and an activating element associated with a cam for displacing the sliding pin into the other position. When the sliding pin is in the retracted position, the internal extremities of the pins abut against one another, their respective surfaces being adapted for providing a space at the periphery thereof capable of receiving the extremity of a position of the cam.

Abstract: The fastening device comprises a housing (1) having joining means to the link, and two coaxial pins (6, 7) for joining it to the object, of which at least one is mounted in a manner that enables it to slide between two positions, one being retracted from the wall of the housing (1) and the other projecting from the wall of the housing (1) for engaging inside an opening of the object, coaxial to a second opening for accommodating the other of these pins. The fastening device also comprises elastic return means (10, 11) for attempting to constantly hold said sliding pin (6, 7) in the retracted position and an activating element (12) associated with a cam (14) for displacing the sliding pin (6, 7) into the other said position. When the sliding pin (6, 7) is in the retracted position, the internal extremities of said pins (6, 7) abut against one another, their respective surfaces being adapted for providing a space at the periphery thereof capable of receiving the extremity of a position of said cam (14).

Abstract: The methods concerns a method for general use and more particularly used for tobacco products. The method uses in particular nitrogen-containing heterocycles such as DNA and RNA bases and complementarily polymer fibers. Said molecules and said fibers can partly halogenated, or in halogenated salt media. The halogen is preferably fluorine. Fluorine may be added to may bei n the form of a medium of fluorinated salts such as NaF, KF, Na2PO3F. The filtering acts against the formation of human intracellular DNA or RNA adducts, while preserving the nicotine and the tobacco aromas.
