Detachable plug connection between two components, namely a socket and a plug, as well as a socket and a plug pipe forming a plug

摘要

The invention describes a detachable plug connection, in particular for inserting a nozzle tube (2) into a bushing (1) which consists of a hollow cylinder (3) and a sleeve (6) mounted displaceably thereon. For this purpose, the nozzle tube (2) is provided with radially resilient tongues (20), the free ends of which bear against a blocking surface (10a). The blocking surface is formed on a flange (10) of the sleeve (6), which is against the force of a spring (24) relative to the hollow cylinder (3) displaceable. To release the connection, the sleeve (6) is pushed back, so that the tongues (20) slide along a cone (14) on the hollow cylinder (3) and are pressed inwards. As a result, the ends of the tongues (20) slide from the blocking surface (10a). As soon as the tongue ends have left the blocking surface (10a), the nozzle tube (2) jumps out of the bush (1) under the action of the spring (24).
