ABSTRACT:
A tube conduit connection and method of producing the same, whereby an end of a pipe made of polyolefin is cold-deformed, i.e. at the ambient temperature, by means of a spreading mandrel. After the spreading mandrel is removed, the enlarged pipe end and a desired connecting piece or the end of another pipe are plugged onto each other. The polyolefin pipe end is then deformed back to the original shape and forms by self-redeformation a solid and gas-tight connection with the connecting piece or the end of the other pipe.
