The process and relative mould enable coupling means (16) to be formed on the walls of plastic containers (10; 10A; 10B; 10C) obtained using an extrusion and blow moulding process. The mould (14), used during the blow moulding step, presents internally, in each position corresponding to that in which said coupling means (16) are to be provided, a peg (18) with an enlarged head (20), extending perpendicularly to the internal wall of the mould (14), to enable a dead hole (22) with an undercut (23), of shape matching that of said peg (18), to be obtained in the container (10; 10A; 10B; 10C). |
