In a quick connection device for piping installed with a checker (), a connector housing () of a quick connector () is formed with opening portions () for inserting resilient legs () therein through the opening portions () in a direction perpendicular to an axis from leading ends of the resilient legs, and inserted portions of the resilient legs () are held inside the connector housing (). The resilient legs () are resiliently deformed in an axially inward direction by an annular projecting portion on an outer peripheral surface of a mating pipe at insertion of the mating pipe, to unlatch latching pawls () of the resilient legs () from corresponding latch portions of the connector housing (), whereby the checker () is allowed to be removed out of the connector housing ().

A fluid line coupling includes a receiving part and a locking part connectable to the receiving part. The locking part includes a plurality of elastically resilient spring tongues engageable behind an annular collar formed on a plug-in part that is insertable into the receiving part. A securing part includes a plurality of elongate securing arms. Guide elements are formed on the securing part and the receiving part that are engagable with one another to displace the securing part in relation to the receiving part. In a securing position of the securing part, each securing arm bears against a respective associated spring tongue and prevents the spring tongue from deflecting outwardly. In this manner, the plug-in part is secured by a very high pull-out force against being pulled out of the receiving part.
