FIELD: construction.
SUBSTANCE: lock is proposed, consisting of a nut designed for interacting with the structure and a locking element interacting with it, that ensures the nut retention. The locking element is represented by integrally formed at least one nut-retaining element and a supporting pad in the form of a plate, enabling access to the threaded opening in the nut, with at least two sidewalls arranged above the nut surfaces designed for interacting with the structure, the sidewalls being designed in such a way that at least a part of each sidewall provides elastic interaction of the lock with the structure, sufficient to attract the nut at least to the structure, both due to the inclination of said sidewall parts from the horizontal towards the nut and due to the properties of the material, from which the locking element is made, and said inclined side parts do not change their surface areas while mounting the lock.
EFFECT: retaining the nut in the given point of a structure groove and preventing its turning over without fastening at installation.
