ABSTRACT:
A quick-action coupling, in particular for refrigerant lines, is provided with a sleeve (1) and a nipple (2) which can be pushed thereinto, with a set of seals (5) having at least one seal (6) of elastomeric material. It has furthermore a locking device (10, 11, 15) for the coupled position between sleeve (1) and nipple (2), which locking device has a bead (15) on the nipple (2) projecting in particular radially outwards and a cage (10) mounted in the sleeve (1), with retaining fingers (11) which can be opened out and engage behind the bead. A releasing tool (25) for opening out the retaining fingers (11) of the cage (10) is provided, which tool can be fitted onto the nipple (2) and can be pushed in in the direction of the sleeve (1). There is provided on the outer circumference of the sleeve (1) a radially outwardly projecting border (30). The releasing tool (25) had a radially inwardly directed collar (29), serving as a stop. The releasing tool (25) has a sleeve-like, essentially axially extending expanding collar (31) for the retaining fingers (11), which collar forms with the projecting bead (15) of the nipple (2) a stop for limiting the drawing-off movement when releasing the quick-action coupling. There is provided on the nipple (2), in assignment to the nipple-side end of the sleeve (1), a circumferential depression (19) onto which a dust-protection ring (18) of elastomeric material is displaceably fitted.
