Disclosed is a self-locking fastening device comprising a screw or nut for fastening at least one first part to a sec-ond part and a shim (10) which is provided with a central borehole (11). The two surfaces of said shim (10) comprise means (12,14) which are fixed within or to the surfaces of the first part and the screw or nut no later than the time that the fastening device is tightened such that self--actuated unscrewing is prevented. The shim (10) is configured in a resilient manner such that said shim (10) can be com-pressed counter to the resilience thereof during tightening of the fastening device.
L'invention concerne un dispositif de fixation autobloquant, comprenant une vis ou un écrou servant à fixer au moins un premier composant à un autre composant. Ledit dispositif de fixation présente une rondelle de calage (10) pourvue d'un orifice central (11) et comportant, sur ses deux surfaces, des moyens (12, 14) qui, au plus tard lors du serrage du dispositif de fixation, se calent dans la couche superficielle ou sur la surface du premier composant et de la vis ou de l'écrou, de façon à empêcher que le dispositif de fixation ne se desserre tout seul. A cet effet, la rondelle (10) est conçue de manière élastique afin de pouvoir être comprimée, lors du serrage dudit dispositif de fixation, avec une force qui s'oppose à sa force élastique.
