Abstract

A connection device (1) for at least one plug-in portion (3) comprising an annular external groove (2) comprises a housing (7), into which at least one plug-in portion (3) can be plugged, and also atleast in each case one integral locking element (9) and a securing device (15). A locking element (9) comprises a securing portion (11) and a locking portion (10) which can be preassembled in the housing (7). In the preassembled state, the locking portion (10), by elastic deflection, permits a plug-in portion (3) to be plugged into the housing (7) and brings about the locking of said plug-in portion in the housing (7). By means of the securing device (15), the securing portion (11) can be secured on an outer side of the housing opening (13) against displacement in a circumferential direction (14). A securing device (15) is designed as a ring which engages around the housing (7) and is movable on said housing (7) at least axially counter to a resistance and has an axial recess (16) in a plugging-in direction (8). A cam (17) arranged on the securing portion (11) of the locking element (9) engages in said recess (16), as a result of which displacement of the locking element (9) in relation to the securing device (15) is prevented.

Description

field of invention [0001] The invention relates to a connection device for at least one insertion part associated with a hose-like or tubular line or a nozzle or a molded body comprising an annular outer groove, said connection device comprising a corresponding insertion part into which The housing therein and the flexible locking element which can be pre-installed in the annular inner groove of the housing. In a pre-mounted state with elastic deflection, the flexible locking element enables insertion of the insertion part into the housing, wherein the locking element latches in an outer groove of the insertion part. The locking element is fixed in the mounted state against displacement of the inner groove in the circumferential direction. technical background [0002] WO 2011 / 060967 A1 relates to a connecting device of the stated type, which fixes the locking element by means of a fixing device, at least against a displacement in the pull-out direction. The securing means...
