Abstract

PURPOSE: To improve and facilitate forming and connection of a plastic tube's socket and spigot, by making longitudinal channels in the substantial tube wall except for both ends, for example.
CONSTITUTION: Longitudinal channels 3 are made in the substantial wall of the middle portion 2 of a plastic tube and its both ends 1a, 1b are remained substantial. The cross sectional shape of the channel may freely be selected: circular, rectangular or triangular. One end 1a, that is, socket, is tapered as shown in the figure and the other end 1b, that is, spigot is expanded from inside. This type of tube construction allows to form its socket and spigot without corrugation on both surfaces with enough thickness and facilitate precise connection of the socket and spigot.
