<p>The flexible hose is enclosed by a flexible metal hose with a screw coupling for connection to a mutually operated tool. Into the hose end is pressed a sleeve with a collar holding a screw coupling part. The hose end is clamped externally by external sleeve in the internal sleeve region. The rotating movements of the hand tool are not transmitted to the hose. The inserted sleeve (3) has on its free end a guide arrangement (7). The screw coupling part (11) is able to rotate on the guide freely. A sealing ring (10) is placed between the guide and the screw coupling, with the sealing ring held within a circumferential groove.</p> |
