Abstract:
A releasable plug connection with a tubular plug-in part, and with a sleeve-shaped receiving part which has an insertion opening through which the plug-in part is insertable into a sleeve interior of the receiving part. At least one annular groove is provided on the inner circumference of the receiving part, in which an annular seal is arranged which provides sealing in the annular gap between the inner circumference of the receiving part and the outer circumference of the plug-in part. The insertion opening opens out in a first interior portion of the sleeve interior that is configured as a cross-sectional widening in relation to an adjacent second interior portion and is delimited by an annular shoulder, and an insertion sleeve is insertable in the first interior portion of the sleeve interior, its peripheral edge directed towards the annular shoulder being spaced apart from the annular shoulder to form the annular groove between the peripheral edge of the insertion sleeve and the annular shoulder.
