The invention relates to a mechanism for securing the handle or knob (9) of a door or window, comprising a locking element (18) that is disposed at an angle to the axis of the handle or knob (9). A locking spring element (13) is disposed in a base part or a knob shield (1). Said locking spring element carries locking lugs (8, 7) that dip into radial openings (2, 6) of the base part or the knob shield (1). The locking element (18) interacts with the locking spring element (13) in such a manner that the locking spring element (13) is deformed when the locking element is displaced at an angle to the axis of the handle or knob (8) and locking lugs (8, 7), disposed on the periphery of the locking spring element (13), disengage from or engage with recesses (10) on or in a part of the handle or knob (9) encircling the locking spring element (13) and the base part or the knob shield (1).

L'invention concerne un dispositif de fixation d'une poignée ou d'un bouton de porte ou de fenêtre (9) comportant un élément de fixation (18) disposé perpendiculairement à l'axe de la poignée ou du bouton (9). Selon l'invention, un élément ressort de fermeture (13) est disposé dans une partie de base ou dans une plaque de bouton (1) et porte des tenons de blocage (8, 7) pénétrant dans des passages radiaux (2, 6) de la partie de base ou de la plaque de bouton (1). L'élément de fixation interagit avec un élément ressort de fermeture (13) de telle manière qu'en cas de décalage de l'élément de fixation perpendiculairement à l'axe de la poignée ou du bouton (9), l'élément ressort de fermeture (13) est déformé et des tenons de blocage (8, 7) disposés sur la périphérie de l'élément ressort de fermeture (13) entrent en prise ou se libèrent de la prise avec des cavités (10) présentes sur ou dans une partie de la poignée ou du bouton (9) entourant l'élément ressort de fermeture (13) et la partie de base ou la plaque de bouton (1).
