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.

Quick-action connection for retaining an insertion part in an orifice of a carrier wall, such as for a Bowden cable sleeve at a vehicle wall, comprising: an extension piece having an annular peripheral groove bounded on one end by a radially protruding tenon part, and a retaining ring carried in the annular groove with a first end face facing the tenon part and a second oppositely facing end face, said retaining ring being resiliently flexible in the radial direction to accommodate insertion thereof through a carrier wall orifice and subsequent radial expansion, to a clamping position, with said second end face abutting the carrier wall adjacent the orifice and the first end face abutting the tenon part, wherein the retaining ring is a slotted meander-shaped ring with slot-like recesses extending axially from both axial ends of the retaining ring, said slot-like recesses and the wall thickness of the retaining ring being configured to provide different radial restoring forces at respective different axial locations of the retaining ring, wherein said retaining ring is conically tapered from a maximum diameter at its end facing the carrier wall when in an inserted position, and wherein the slot-like recesses at the end adjacent the maximum diameter of the retaining ring are axially shorter than are the slot-like recesses at the opposite end of the retaining ring.
