The locking facility incorporates an external first track passing around the periphery arranged on the male part, a lock ring fitted in the first track and a first release part (22) arranged in the female part. The lock ring is arranged with an axial slot with a specific height in the lock ring peripheral direction. The lock ring is made of spring steel. The male part provides a threaded coupling between it and the female part and has a longitudinal through-running bore for flushing medium and an external thread with works in conjunction with an inner thread (18) in the female part.
