Abstract: The lock comprises a ring (20) which encloses the connection (3), and can move relative to it. The ring should be slotted out (21) between inside and outside so that the plug-in part of the fluid line (9) passes through a first slot sector (22) as directed towards the plug-in hole (7). A second slot sector (23) joined to and is narrower than the first so that when it is lined up with the hole, part of the ring engages the inserted part's plug's (12) stop face (16), preferably grasping round this face so as to prevent the plug from being pulled out. The ring has a third slot sector (24) connecting the other two which at one point limits a narrow passage (25). This passage is narrower than the plug, but the passage walls spread resiliently apart to admit the plug initially. The ring itself should be made of glass-fibre reinforced plastics and encloses the connection, its slots being offset from one another round the ring.

Abstract: Locking arrangement of a fluid insertion connection between a fluid line and a connection member, in particular between a hydraulic line and a hydraulic cylinder, the fluid line having an insertion part at one end and the connection member being provided with an insertion opening which is open at the circumferential surface of the connection member and receives the insertion part of the line. Furthermore, locking means are provided, which engage on an abutment surface of the insertion part of the fluid line in order to prevent the insertion part of the line from being pulled out of the insertion opening. The locking means comprise a ring, which is positioned around the connection member at the position of the insertion opening and is movable with respect to the connection member. The ring has a slot extending between its inside and its outside, which slot comprises a first slot part, through which the insertion part of the fluid line fits when the first slot part of the ring is aligned with respect to the insertion opening, and a second slot part, which is connected to the first slot part and is narrower than the first slot part, so that when the second slot part of the ring is aligned with respect to the insertion opening, part of the ring engages on the abutment surface of the insertion part which has been inserted into the insertion opening, as a result of which the insertion part is locked so that it cannot be pulled out.
