Plug-in pipe connection - has one wider end gripping over the pipe and other end outwardly bent back and milled, with sprung tongues on sleeve

摘要

The plug-in connection for pipes (1, 2) has at least one end (1`) of the first pipe (1) gripping over one of the ends of the second pipe (2). The first pipe (1) end (1`) is wider over the part gripping over the second pipe (2). The first pipe (1) other, free end has an outwardly bent-back milled rim (3). The second pipe (2) plug-end (2`) is recessed and has springy tongues (4) protruding from the pipe outer surface. The tongues (4) stick out from a sleeve (6) riveted or welded to the second pipe (2) outer casing. USE/ADVANTAGE - The two pipes are quickly assembled together and resist longitudinal forces.
