Abstract: A connecting device for media lines including a coupling element, an insert part and a fastening element. The coupling element has a connection opening and a fluid channel; the insert part can be inserted into the connection opening; and the insert part can be fastened to the coupling element by the fastening element. The fastening element also has at least one control surface. When the insert part is inserted into the connection opening under the action of an installation force, the insert part acts upon the control surface in such a way that the fastening element is moved against a restoring force. If the installation force is sufficient, the insert part slides past the control surface and the fastening element interlockingly locks the insertion part. If the installation force is not sufficient, the fastening element presses the insert part back out of the connection opening.

Abstract: A connection device for pipe lines includes a connection element that has a receiving opening for a pipe line and a retainer element that stops the pipe line from being pulled out. The retainer element is designed as a spring-elastic toothed ring that has teeth distributed across a circumference and which extend radially inward at an incline and act against the pipe line. The toothed ring is mounted to have limited axial play. At the transition region between an outer circumferential region and the retainer teeth, the toothed ring interacts with a circumferential tilt edge such that the toothed ring can pivot about the tilt edge out of a position in which its outer circumferential region is pressed against a first, lower contact section and a second, upper contact section. The retainer teeth being able to be elastically deformed by bending.

Abstract: A connecting device for media lines, having a housing part, which is formed in two parts from a receiving part for plug connection of a media line and from a connecting part for connecting the housing part to a unit or an additional media line. The connecting part is connected to the receiving part via a coaxial rotationally symmetrical plug connection with form-fitting engagement and with a peripherally closed line progression. The connecting part is inserted with an insertion projection into a plug receptacle of the receiving part, wherein the insertion projection reaches with a radially outward protruding catch step in a form-fitting manner behind a radial undercut surface inside of the plug receptacle.

Abstract: A construction system for a connection arrangement for media lines, wherein the connection arrangement has a connection body with a receiving opening for a media line and with internal parts for interacting with the media line and providing axial guidance, mechanical locking to prevent detachment, peripheral sealing and, where applicable, internal radial support. Various internal parts can optionally be inserted into the connection body, which is designed to be identical in respect of the internal contour of the receiving opening, and for a particular maximum external line diameter, in order to adapt to at least two dissimilar media lines having different cross-sectional dimensions. The internal parts are adapted, on the one hand, to the permanently identical internal contour of a receiving opening of the connection body and, on the other hand, to the cross-sectional dimension of one of the dissimilar media lines.
