RAPID CONNECTION FLUID COUPLING HAVING SHUTTER AND TOOL USED THEREFOR

摘要

A rapid connection fluid coupling includes first and second end pieces. The first end piece is adapted for fitting to a duct or the like such as in the cooling liquid circuit of a motor vehicle engine. The first end piece includes a closure or seal coaxially positioned therein for sealing the flow path through the first end piece when the second piece is not connected thereto. A perforator is supported by the first end piece and positioned in the fluid passageway of the first end piece for perforating the closure when the second end piece is interconnected to the first end piece.
