FIELD: engineering industry.
SUBSTANCE: attachment element includes two side walls and base. Side walls are made from material with shape memory effect property, located at an angle to each other and they have oblong-shaped slot in their central part at the point of their attachment to each other. Bases are made in the form of blades attached to side walls and directed outwards.
EFFECT: providing attachment of parts or fragments of part, which are compound as to the shape and detached because of crack, there is possibility of drawing attachment parts or crack edges together, providing transverse stiffness of designs at attachment point, eliminating mutual offset of parts or crack edges in transverse direction.
