A shock-, vibrations- and tampering-proof attachment means of an object, h as a signal producing insert of an ionization alarm system coaxially and non-rotatably to a support, such as for land-, marine- and air vehicles provides a spring assembly with a spring and biased coaxial protrusion in the bottom of the object with a helically wound canal running through the protrusion having end orifices in its surface. The support is provided with a U-shaped fork fixed with its yoke in it. A connecting means equipped with a rod traverses the protrusion perpendicularly to its axis. The rod is fastened to both free ends of the yoke. Optimum shapes and dimensions of the respective parts are established, also with the view of maintaining a minimum size of the object itself. The object with the fixed protrusion is mounted by rotation thereof to the support, thus hiding the attachment means and making them vibration proof and inaccessible from the outside. An attempt to disassemble the attachment by re-rotation of the object relative to the support results only firstly in moving the point of engagement of the attachment upwardly toward the vertex of the canal, simultaneously distancing the protrusion from the spring assembly and subsequently reversing the axial motion of the protrusion toward the spring assembly with the point of engagement of the attachment continuing to move to the end of the canal or channel, thus preventing axial separation and a reverse rotation without excessive force.
A shock-, vibrations-, and tampering-proof attachment means of an object, such as a signal producing insert of an ionization alarm system coaxially along a common central axis to a fixed support face of a support, such as of land-, marine- and air-vehicles,
