FIELD: mechanical engineering.
SUBSTANCE: device comprises L-shaped ring (4) that is interposed between nut (6) and washer (3) and embraces stud (1) with a spaced relation to it. The cylindrical section of the ring is in a contact with the inner side of washer (3). Stud (1) has cylindrical collar (8) that is in a contact with the inner side of washer (3) under L-shaped ring (4). Between shelf of L-shaped ring (4) and washer (3) is spacer (7) made of a flexible material, e.g. aluminum. Between washer (3) and lag (2) is additional washer (5) whose spherical surface is in a contact with washer (3).
EFFECT: enhanced reliability.
