Abstract

Le dispositif comporte une goupille de sécurité 16 qui peut être introduite à travers un perçage radial de l'écrou 2 et qui, dans sa position de blocage, pénètre dans une fente axiale du boulon fileté. L'écrou 2 comporte un élément-boîtier 10, 20 qui forme une protubérance radiale vers l'extérieur à la maniere d'une poignée et qui présente un alésage central 12, dans lequel la goupille de sécurité 16 est disposée et précontrainte, par un ressort 22. Un organe de manoeuvre 32, en saillie au-dessus de l'élément-boîtier, est fixé sur la goupille de sécurité et permet de retirer celle-ci, contre l'action du ressort, de la fente axiale 26 du boulon fileté 4.The device comprises a safety pin 16 which can be introduced through a radial bore in the nut 2 and which, in its locking position, penetrates into an axial slot of the threaded bolt. The nut 2 comprises a housing element 10, 20 which forms a radial protuberance outwards like a handle and which has a central bore 12, in which the safety pin 16 is arranged and prestressed by a spring 22. An actuator 32, projecting above the element-housing, is fixed on the safety pin and allows the latter to be withdrawn, against the action of the spring, from the axial slot 26 of the bolt. threaded 4.
