Patent ID: 8075022

Claim:
A fluid technology device comprising: at least one connecting body, the connecting body having at least one fluid-carrying conduit extending therethrough and terminating at an exterior of the connecting body in a connecting opening; at least one elastic fluid-carrying hose with elastomeric properties, which is or can be connected with the at least one fluid-carrying conduit; and a connecting arrangement for connecting the fluid-carrying hose with the fluid-carrying conduit by a plug-in connection, wherein the connecting arrangement comprises a holding slide, which is or can be seated on the connecting body so that the holding slide is displaceable in the direction of an actuating axis extending transversely in respect to the longitudinal axis of the connecting opening, the holding slide having a pass-through opening extending therethrough, the pass-through opening having an insertion section and a holding section, the holding section being narrower than the insertion section and adjoining the insertion section in the direction of the actuating axis, wherein the holding slide can be selectively positioned in a release position, in which the pass-through opening is aligned with the connecting opening, and in a holding position, in which the holding section is aligned with the connecting opening, and wherein the connected fluid-carrying hose itself is directly plugged through the pass-through opening of the holding slide into the connecting opening of the connecting body, and wherein the width of the pass-through opening in the area of the insertion section is greater than the nominal exterior diameter of the fluid-carrying hose, and the width of the pass-through opening in the area of the holding section is less than the nominal exterior diameter of the fluid-carrying hose such that, in the release position of the holding slide, the fluid-carrying hose can be passed unhindered through the pass-through opening into the connecting opening and can be pulled out of the pass-through opening again, and that, in the holding position of the holding slide, the fluid-carrying hose is clampingly fixed in place in a manner whereby a hose wall of the fluid-carrying hose is deformed by slide sections, which laterally delimit the holding section, but wherein a fluid through-put through the fluid-carrying hose is not substantially restricted.
