Abstract

A method and apparatus are provided for quickly connecting a handpiece (400) to a pressurized fluid source (300). A hollow tube on the handpiece (400) is inserted through an aperture in an annular (100) gasket which is held in a chamber (500) in a body. On application of pressurized fluid to the body, the gasket is pressed against the walls of the chamber, and against the tube, thereby channeling the pressurized fluid through the hollow tube. The handpiece is retained in connection with the body by a releasable connector, such as a latch (944). The handpiece can be removed and replaced by releasing and remaking the connection.
