FIELD: mechanical engineering; liquid pipelines.
SUBSTANCE: invention relates to connecting device with coaxial end sections of two liquid passing pipelines to be connected, each of which is provided with stop rib on end section with bushing which is provided with slot and joint arranged opposite to slot. Bushing has stops on its inner side for engagement with stop ribs by fitting into grooves. Joint is made flexible so that it loads parts of bushing near slot in direction towards each other. End sections are made for fitting into bushing in axial direction at elastic expansion of slot by sliding of stop ribs under stops top provide fixing behind stops. Axial width of stops corresponds to width of grooves.
EFFECT: improved reliability of connection of pipelines.
