A releasable plug connection for inserting a nozzle tube into a jack includes a hollow cylinder and a sleeve displaceably mounted on the cylinder. A nozzle tube, forming the hollow cylinder, is provided with radially spring-loaded lugs, the free ends of which are in contact with a locking surface. The locking surface is formed on a flange of the sleeve, which can slide relative to the hollow cylinder against the force of a spring. To release the connection, the sleeve is pushed back so that the lugs are pushed inwardly, and ends of the lugs slide from the locking surface. As soon as the lug ends have left the locking surface, the nozzle tube shoots from the jack under the action of the spring. |

1. A releasable plug connection, which is either in a connected or released state, comprising:
a jack, and a plug, wherein, in the connected state, the plug is inserted into the jack and held in it by a lug standing out with respect to the plug at an acute angle, for the purpose of which the lug is connected with the plug in a radially spring loaded manner and contacts a locking surface formed on the jack, as a result of which sliding back of the plug out of the jack is prevented, wherein the locking surface extends largely radially to the longitudinal axis of the jack and the plug, and the jack consists of a hollow cylinder and a sleeve surrounding part of the hollow cylinder that can be displaced by relative axial sliding with respect to each other to a limited extent in an axial direction, wherein the locking surface is formed on a flange at one end of the sleeve, and the hollow cylinder has a contact point for the lug which cooperates with the lug on pushing together of the hollow cylinder and the sleeve against the force of a spring acting in the axial direction, and wherein the plug, to which the lug is connected, and the lug move relative to the jack so that the lug contacts the contact point and is pushed from the locking surface in a radial direction by sliding on the contact point to allow withdrawal of the plug from the jack. |
