Abstract
A quick-coupling fitting for pipes comprises a female element and a male element that can be coupled together. The female element comprises parts that are fixed and parts that can slide between a closed position and an open position of a passage for fluids. The fixed parts comprise a stem having one end enlarged, and the slidable parts comprise a bush, coaxial with the stem, axially slidable and elastically urged towards the closed position. The bush defines with the stem a hollow space for the passage of the fluid. The bush is provided with a sharp-edged metal annular projection that, in the closed position, engages with a metal frustum-shaped surface of the enlarged end of the stem to provide a seal of said hollow space.
