Abstract
In a rapid coupling, an end section of a pipe nipple engages in a throughhole of a sleeve. A groove provided on the pipe nipple serves to engage a resilient locking ring formed in the sleeve in order to lock the coupled state. The locking ring is located in an annular recess formed close to the insertion end of the sleeve. If the pipe nipple is not inserted into the bush to such an extent that the locking ring latches in the groove, the pipe nipple is pushed outward by a compression spring provided in the throughhole of the sleeve, so that the groove is readily visible outside the sleeve. The groove thus serves not only for locking in the properly coupled state but also as an indicator for indicating a state which is not properly coupled.
