Title: (EN) Coupling
Abstract: front page image
(EN)

The invention relates to a coupling comprising a receiving part (1) and a fixing part (10), which have a blocking assembly (15, 16, 17). If the insertion part has not been introduced into the receiving part (1) correctly, elements (15, 16, 17) of the blocking assembly that are configured on the receiving part (1) and on the fixing part (10) engage with one another in such a way that the fixing part (10) is prevented from being retracted from the extended position. Arms (11, 12) of the fixing part (10) are configured in such a way that when a retaining ring of the insertion part is positioned in the vicinity of said arms (11, 12), the engagement of the elements (15, 16, 17) of the blocking assembly is released and the fixing part (10) can be displaced into the retracted position to engage behind the retaining ring by means of the retraction section. This permits an efficient mounting operation.
