A blow-moulded hollow body has an insert anchored in a wall of the hollow body by wall portions which penetrate openings in a projecting portion of the insert from both sides during the blow-moulding process and which are welded together at these openings. A wall portion of the hollow body is afterwards cut away to form an access opening and the insert is adapted to receive a closure cap for this opening. In another embodiment, the insert has a carrying handle attached thereto.
