Quick-action coupling, in particular for refrigerant lines

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