摘要： A tank assembly utilized in a heat exchanger such as a radiator and the method of connecting a cylindrical spout such as a filler tube in an opening in the tank wall. An opening is formed in the tank wall with a skirt extending inwardly from the tank wall. A plurality of cam/lock sections are formed at the lower extremity of the skirt with each cam/lock section having a cam surface leading from a receiving end to a locking recess, the opposite wall of which is extended to define a stop. A plurality of radial slots are formed in the tank wall to extend radially of the skirt adjacent the receiving ends of the cam surfaces. A spout is formed having a radially extending shoulder and a lower portion with a plurality of radially extending tabs. An annular seal recess is disposed in the tank wall for receiving a seal. The spout is inserted into the opening by passing the tabs through the slots to engage the tabs with the receiving end of the cam surfaces and the spout is rotated to move the tabs along the cam surfaces until they snap into position in the locking recesses to compress the seal between the shoulder in the spout and the seal recess.
