AI Technical Summary
Technical Problem
Existing couplings for corrugated pipes suffer from reliability issues due to cracking at the attachment point of the lock plate under low temperature conditions, leading to potential failure and loss of fixation.
Method used
A coupling design featuring two coaxially installed bushings with projections on the inner bushing that can elastically displace into holes in the outer bushing, accompanied by material weakening to reduce stress concentration, ensuring reliable fixation even at low temperatures.
Benefits of technology
The design minimizes the risk of failure at the lock plate attachment by allowing elastic deformation and stress relief, enhancing the coupling's reliability and durability.

Abstract
This utility model relates to couplings for corrugated pipes. The technical result consists of increasing the coupling's reliability.For this purpose, the coupling for a corrugated pipe is made in the form of two bushings coaxially installed one inside the other, wherein openings are made in the wall of the outer bushing, and elements protruding above the outer surface of such a bushing are formed from the walls of the inner bushing, with projections on the surface facing the inner space of such a bushing, and made in such a way that the possibility of their elastic displacement towards the inner space of such a bushing is ensured when the outer bushing is displaced along the surface of the inner bushing due to the action of the walls of the outer bushing on them, and when the outer bushing is displaced along the surface of the inner bushing until the openings in the wall of the outer bushing and the projections on the inner bushing are aligned, the elastic return of such projections to their original position is ensured due to their placement in the said openings of the outer bushing, wherein in the area of the connection of the projection of the inner bushing with its wall, a weakening of the wall material is made. 3 c.p. phyl., 3 fig.
