A coupling sleeve can be coupled together with a nipple 16 by means of a ball lock 24 in order to interconnect two tubes. The coupling sleeve has a sleeve-shaped front part 14 which is inserted telescopically into and can be rotated relative to a sleeve-shaped rear part 12. The front part and the rear part are axially locked to one another by a locking ring 32 which is mounted rotatably in two grooves, an internal annular groove 36 in the rear part and an external annular groove 34 in the front part. If the ball lock is blocked by dirt, rotatability is maintained at the locking ring. <IMAGE> |
