The invention relates to an arrangement related to a coupling for releasable connection of a coarse hosepipe to a container, in particular a so-called bottom filler coupling for tank vehicles or similar, said coupling comprising a male part intended for fixed mounting at the container and a female part, lockable to the male part by twisting it in its affixed position and being intended for permanent and butted joining with the hosepipe via a swivelling sleeve which encompasses an extension of the female part in a liquid-tight manner and is rotatable around said extension in order to avoiding twining of the coarse hosepipe when locking and releasing the female part, respectively, to and from the male part, respectively. The arrangement, which aims at eliminating leakage between the extension of the female part and the swivelling sleeve at the breakage actions occurring during the use of the coupling, consists of an improved journaling between the swivelling sleeve and the female part extension, whereby a ball circuit is arranged between the outside of the part of the swivelling sleeve situated most inward over the female part extension and the inside of an outer bearing race fastened to the female part and concentric with the female part extension, whereby the swivelling sleeve furthermore has an annular end face abutting the female part and having a large radial extension. |
