ABSTRACT:
An improved quick-coupling assembly for fluid conduits comprising a first sleeve portion, which is connected to a first conduit and at its free end is slotted thus forming a number of resilient tongues and a second sleeve portion, which is connected to a second conduit and in which a part of the first sleeve portion is intended to be received. For locking the two sleeve portions together an external collar is provided on the resilient tongues of the first portion, said collar being intended to be locked behind an interior shoulder in the second portion. When the coupling is to be disconnected, the first portion is pushed further inwardly in the second portion, at which a ring having a substantially triangular cross-section and being arranged in and being axially displaceable in the second portion cooperates with the resilient tongues compressing them, so that the collar can be moved past the shoulder when the first portion is pulled outwardly.
