CONNECTION DEVICE FOR CORRUGATED HOSE Russian patent published in 2012 - IPC F16L25/00 

FIELD: construction.

SUBSTANCE: invention is related to connection devices with a connection part, and also arranged with the possibility to insert an insert part in it, which on its external surface has fixing ledges that protrude outside, the connection part is equipped with radially stretching fixators arranged accordingly to the location of the fixing ledges on the insert part, and those fixators during the axial input of the insert part into the connection part pass through the accordingly related fixing ledge by elastic radial deviation, and then radially sag again directly axially behind the fixing ledge. The connection part comprises an inner retention device, through which the corrugated hose is through-conductible in direction of the insert part, and at the same time it performs elastically springing radiation movements, but prevents hose tightening. The corrugated hose juts out until stop into a sealing bush with an axial throughput channel installed inside the insert part. In the coupled condition the retention device of the connection part axially juts out into a reversed receiving hole of the insert part, is blocked against uncoupling of the corrugated hose, and is in direct clamping contact with the sealing bush.

EFFECT: increased operational reliability.
