MULTICOMPONENT CONNECTING NODE Russian patent published in 2022 - IPC F16L33/30 

FIELD: engineering elements.

SUBSTANCE: invention relates to a multicomponent connecting node. The connecting node comprises a first retaining element (10) configured to engage with the pipe coupling (50), a second retaining element (20) configured to engage with the hose (40), and a sealing element (30). The first and second retaining elements (10, 20) are distanced from each other along the axial direction of the connecting node, and the sealing element (30) is located between said retaining elements in the axial direction. Said first retaining element (10) herein is also adapted to engage with the hose (40); and the sealing element (30) is configured to increase in diameter and form a seal with the inner surface of the hose (40) and the outer surface of the pipe coupling (50) when the coupling (50) is inserted into the first and second retaining elements (10, 20).

EFFECT: compact snap-on connection of a hose (40) with a pipe coupling (50) with only one potential leakage point.
