DETACHABLE JOINT OF HIGH-PRESSURE PIPELINES Russian patent published in 2007 - IPC F16L37/84 

FIELD: detachable joints of high-pressure pipelines, namely in brake drive circuits of motor vehicles.

SUBSTANCE: detachable joint includes cylindrical housing with central mounting opening and tubular insert part provided with circular locking rib. At side of introducing insert part to housing its mounting opening is in the form of enlarged mounting opening for several radially unclamping fixing members arranged in it. Said fixing members are preliminarily tightened one to other in direction of inner space of housing by means of springy ring. Fixing members have two ring halves with directed inward along radius wedge stops. Said stops are displaced behind its locking rib at geometry closing after introducing insert part into housing. Each ring half has in its one end protruding guiding pin being extension of inner wall. At assembling one to other ring halves said pin enters reciprocal recess in other end respectively of other ring half. After introducing ring halves into housing, front edge of housing wall restricting enlarged mounting opening is bent inwards along radius at inclination relative to housing axis, possibly by such value that locking rib may enter without interference. Said ring halves may freely unclamp along radius outside at introducing insert part into housing.

EFFECT: enhanced reliability of detachable joint.
