摘要： The invention relates to a quick coupling, wherein a tube nipple (11) engages in a passage bore of a bush (10). A first annular groove (15) provided on the tube nipple (11) is used for the engagement of a locking ring present in the bush (10) in order to lock the coupled state. A sleeve (12) can be slid onto the tube nipple (11), which sleeve is fixed on the first annular groove (15) of the tube nipple (11) by means of an inner projection (21) in a pre-mounted state. When the tube nipple (11) is inserted into the bush (10), the sleeve (12) hits the bush (10) and is then slid along the tube nipple (11) until the inner projection (21) snaps into a second annular groove (17) in the case of correct locking of the coupling. If the tube nipple (11) is not inserted into the bush (10) so far that the locking ring locks into the first annular groove (15), the second annular groove (17) remains visible outside of the sleeve (12) in order to indicate the improper coupling state.
