International ClassF16L 021/06Foreign Application Priority Data1999-07-26 DEAbstractA socketless fitting for releasable connection of a pressurized line. The fitting has a housing body with a receiving opening to insert one end of the line, and an inner sleeve attached in the housing body in an arrangement that extends coaxially within the receiving opening for engagement into the inserted line end. The inner sleeve is fastened in the housing body media-tight around the periphery by a connector and preferably engages in the line media-tight around the periphery. A clamping element axially movable in the receiving opening cooperates with an inner surface of the housing body to secure the line end onto the inner sleeve. Media-tight outward sealing is accomplished by sealing engagement of the essentially rigidly secured inner sleeve in the line, because the inner sleeve itself is also tightly joined to the housing body. | |
