FIELD: sewerage.
SUBSTANCE: group of inventions relates to sewage equipment. Connecting device (1) comprises annular gasket (12), end fastening element (13), made with possibility of movement between at least receiving position and fixation position, compressing elements (14) of annular gasket. Inner diameter of annular gasket (12) provides free movement of the second pipe in the end fastening element located in the receiving position. Movement of end fastening element from receiving position to fixation position leads to radial, at least directed to centre, deformation of annular gasket (12) by means of compressing element (14), characterized by availability of chamfered element (140) acting along circumference of annular gasket with reduction of its inner diameter for its pressing to the second pipe in order to keep the latter in seat. Annular gasket (12) is located in end fastening element (13) and is rigidly connected to it and is characterized by presence of edge passing parallel to axis of insertion of second pipe in seat (11), wherein outer edge of edge is bevelled, and its shape is complementary to the shape of bevelled element (140) of the connecting means located on the front of the seat. Connection means comprises means (3) for fixing end fastener (13) on the pipe to secure the end fastener. Connecting device comprises pipe (10), on both ends of which there is connecting device (1) described above. Plug-type device includes pipe (10), one end of which is closed, and the second one contains the above-described connecting device.
EFFECT: fast and high quality assembly.
