Quick release coupling for pipe carrying refrigerant

摘要

The coupling comprises a release tool (25) which has a radially inwardly directed collar (29) serving as a stop. On the outer circumference of the sleeve (1) a radially outwardly projecting edge (30) serves as a counter stop for the collar stop. The release tool has a sleeve-like axially extending widening collar (31) for the holding finger (11) which together with the projecting bulge (15) of the nipple (2) acts as a stop to restrict movement on releasing the coupling.
