1. An adapter assembly for connecting a fluid supply assembly to a fluid applicator comprising:
- an outer lid for the fluid supply assembly, the outer lid having an integral generally cylindrical fitting with an opening therethrough, the fitting having a tab at an upper end and a horizontal stop at a lower end; and
an adapter having a first end and a second end, and a bore between the first end and the second end, the first end having a connecting surface adapted to mate with a complementary connecting surface on the fluid applicator, the second end having a portion having a first shape and a portion having a second shape, the portion having the first shape being adapted to pass by the tab so that the second end can be inserted into the fitting, and the portion having the second shape being adapted so that it cannot pass by the tab, the second end having a height so that the second end fits between the horizontal stop and the tab of the fitting, whereby when the adapter is rotated, the portion having the second shape is retained under the tab so that the adapter is locked to the outer lid.
