Filler tube for liquid containers

A crimping tool for mechanically attaching a tube having an axial bore to a tank, comprising:

• a housing including a bore portion and means for positioning a retainer which includes at least one extending metallic lug;
• a ram assembly including guide means for aligning said ram assembly within the axial bore of said tube, said guide means including a bore portion and a plurality of apertures along said guide means;
• and
• means for expanding a portion of said tube radially outwardly including a selectively actuable ram member having a frustoconical head disposed at least partially within the bore of said guide means and a plurality of outwardly displacable bearings disposed within said apertures;
• whereby upon positioning said housing over said tube such that said guide means extends into the tube and the retainer is properly aligned, upon actuating said ram member to increasingly engage the bearings said bearings are displaced outwardly through the apertures thereby expanding a portion of said tube radially outwardly.
