This is a remixed version of the extruder multi clip but smaller to suit the E3D bowden locking ring fitting. This prevents the locking ring from moving in and out
...Show more of the extruder/hotend which prevents poor filament control especially when retracting/unretracting.
Slide the clip into place before inserting the bowden tube and you'll have a tight fit with no play from the start. Unclip it to remove your bowden tube.
