ABSTRACT:
This invention is a quick connecting and disconnecting assembly for standard dental handpieces that are normally connected to a supply line by base nut sleeves that are screwed onto the threaded end of such handpieces. This is accomplished by simply replacing the interiorly threaded base nut on the supply line with a base locking sleeve having j-shaped slots in the outer end thereof and telescoping this over an interiorly threaded connector sleeve with exterior lugs thereon mounted on the threaded end of the handpiece so that the lugs can engage the j-shaped slots.
