Fluid line coupling

Abstract

The invention relates to a fluid line coupling which has a receiving part (1) and a locking part (15) which can be connected to the receiving part (1) and on which is formed a number of elastically resilient spring tongues (18) which are designed for engaging behind an annular collar (29) which is formed on a plug-in part (28) which is to be inserted into the receiving part (1). Also provided is a securing part (20) on which is formed a number, corresponding to the number of spring tongues (18), of elongate securing arms (22). Guide means (7; 24, 25) are formed on the securing part (20) and on the receiving part (1), which guide means (7; 24, 25) are in engagement with one another for the movement of the securing part (20) in relation to the receiving part (1). In a securing position of the securing part (20), each securing arm (22) bears at the outside against a respectively associated spring tongue (18) and prevents the latter from deflecting outward. The plug-in part (28) is thereby secured, with a very high pull-out force, so as to be prevented from being pulled out of the receiving part (1).
