PROBLEM TO BE SOLVED: To provide a connection element for a pressure tank capable of being manufactured simply at low cost, and surely sealing a pressure tank with high reliability.SOLUTION: A connection element 1 for a pressure tank 10 capable of being inserted into the opening of the pressure tank 10 includes a plug element 2, and fitting elements 6, 7 at least partially surrounding the plug element 2. The outer surface of the plug element 2 and the inner surfaces of the fitting elements 6, 7 form a tapered cut-off part 13. Consequently, a tank wall 3 of the pressure tank 10 enables fastening fixation in the cut-off part of the connection element 1. |
