In order-to prelocking device consists 5,; having the bent ends ing space for the part5; the part 5 being movably mounted is being screwed on to'the casing 2."the piece in Fig. 2. After the cap'has been properly screwed down, thepiece '5 is moved to the position shown in full lines in Figs. 2 and 3, so that the bentends 6. engage the casing 2, thereby preventing the accidentalfloosening of the cap 3.' The piece 5 is preferably of some spring metal which will exert 'a' pressure upon the casingfiwhen in'its operative position. The piece5 may he moved "rnEXiBLn JOINT.
