Abstract
For reasons of technologically simple, economical manufacture, a coupler element for coupling an injection nozzle (11) to a connector neck (12), coaxial with it, on an injection line is embodied as a one-piece plastic clip (10), which comprises a C-shaped annular disk (16) and spring legs (17) protruding away from the annular disk (16) in the axial direction of the clip and having inwardly oriented detent protrusions (18). With a groove engagement region, the annular disk (16) engages a circumferential groove (15) in the injection nozzle (11), while after the coaxial insertion of the end of the injection nozzle (11) into the connector neck (12), the detent protrusions (18) snap into place behind a locking collar (14) on the connector neck (12) (FIG. 1).
