ABSTRACT:
In a quick-action connection for retaining an insertion part in an orifice of a carrier, for example a holding nipple in a body wall, there is, in a peripheral groove of a tenon-shaped extension piece of the insertion part, a retaining ring resiliently flexible in the radial direction, which has its largest diameter in the inserted state of the insertion part. The retaining ring partially projects beyond the periphery of the extension piece and is supported on the carrier by means of one of its end faces. So that the retaining ring is capable of guaranteeing a reliable mutual connection of the two parts, even when bending moments are exerted on the insertion part inserted into the carrier orifice with a clearance fit, its annular shell is closed in the peripheral direction and extends in the form of a meander. As a result of this ring design, the retaining ring can be compressed radially in order to introduce the insertion part into the carrier orifice, and after insertion it automatically springs open again. At the same time, by means of its continuously closed and therefore axially rigid annular shell, it is supported on the carrier on the one hand and on the insertion part on the other hand.
