Abstract
A connection device for at least one plug-in portion including an annular external groove includes a housing, into which at least one plug-in portion can be plugged, and also at least in each case one integral locking element and a securing device. A locking element includes a securing portion and a locking portion which can be preassembled in the housing. In the preassembled state, the locking portion, by elastic deflection, permits a plug-in portion to be plugged into the housing and brings about the locking of the plug-in portion in the housing. By means of the securing device, the securing portion can be secured on an outer side of the housing opening against displacement in a circumferential direction. A securing device is designed as a ring which engages around the housing and is movable on the housing at least axially counter to a resistance and has an axial recess in a plugging-in direction. A cam arranged on the securing portion of the locking element engages in the recess, as a result of which displacement of the locking element in relation to the securing device is prevented.
