The invention relates to a plug-in rapid-action coupling device (10) for corrugated tubes (12) which have recesses (22) provided at unit spacings on the outer circumference, having a coupling body (14) with an opening (16) which passes through symmetrically and has an axis (20), having a plug-in region (18), within which the corrugated tube (12) can be arranged, and having at least one elastically deformable latching unit (30) which is provided, in the plug-in region (18), on the wall of the coupling body (14), which is arranged so as to be inclined in the direction toward the axis (20), and which, in the plugged-in state of the corrugated tube (12), latches into a recess (22) which is provided correspondingly on the corrugated tube (12), with the result that the corrugated tube (12) is secured against being drawn out, and said plug-in rapid-action coupling device (10) is distinguished in that, in the plug-in region (18), at least two slits (36), which are spaced apart essentially parallel to one another, are provided in the wall of the coupling body (14), the latching unit (30) is arranged between the slits (36) it being the case that the latching unit has a first spring element (38.1), integrally formed on the wall, and a second spring element (38.2) in each case, and the first and second spring elements (38.1, 38.2), are coupled to one another via a hinge (40) which runs essentially transversely with respect to the axis (20).
