Nut safety

Maticová pojistka (2) je vytvorena ve tvaru prstencového tela (2), které je opatreno cely (8) na nichž je vytvoren bud prilnavý ci lepivý povrch (7). Prstencové telo (2) je opatreno cely (9), která mají vycnívající zoubky (10). Prstencové telo je vytvoreno jako pružinové telo (12, 15) tvorené jedním nebo více závity ohnutého prutu, pricemž alespon jeden závit je pevne propojen v dotykovém míste (14). Prstencové telo je vytvoreno jako pružinové telo (11, 16, 24) tvorené plochým mezikružím. The present invention relates to a system for securing a bolted connection consisting of a body with surface (4) and a bolt (3) passing therethrough and having a bolt head (3) and optionally a nut (1) screwed on the bolt, wherein a ring-shaped safety (2) is pressed between the bolt (3) head, optionally the nut (4) and the body surface (4) along the circumference of the bolt (3) head. Said ring-shaped safety (2) front surface abuts to the body surface (4) and prevents thus the bolt (3), optionally the nut (1) spontaneous loosening. Preferably, the safety abutment of the body surface (4) is secured by adhesive, adherent (7) or serrated surfaces (10) of the safety (2) faces, optionally tongues (13) overlapping or projecting of at least one surface of the safety (2).
