摘要： The present invention relates to a connecting element for liquid-conducting plug-in connections, comprising a flexible hose connecting piece (2) which is formed by a connecting piece (1) inserted into the connecting end of a flexible plastic hose (3). Said element has a conically extending plug-in chamfer (4) on its open end and a cylindrical shank (5) connected thereto with multiple truncated spherical extensions (6) and (7), in addition to a ring-shaped stop flange on the end of the plug-in area (E), wherein a conical taper (9) is connected on the rear side of the first truncated spherical extension (6). A peripheral groove (10) is provided in-between the extensions (6) and the taper (9). A sealing ring (11) with a round cross section is embedded in the groove. In order to facilitate placement of the end of the flexible hose or tube on the connecting piece, the jacket surface (M1) of the first truncated spherical extension (6) has an angle of aperture alpha of approximately 45 DEG in relation to the jacket surface of the shank (5), bypassing by a small margin (a) the external jacket (14) of the sealing ring (11), while the jacket surface (M2) of the following taper (9) has a considerably flatter angle of inclination beta of 20 to 30 DEG in relation to the jacket surface of the shank (5), being tangent to the outer surface (14) in respect to its rear extension.
