Capable of being clipped; able to be cut, trimmed, or fastened with a clip.
From 'clip' (Old Norse 'klippa') plus '-able' (capable of). This modern English formation follows productive adjective-building patterns.
The word 'clippable' only works in certain contexts—dog hair is clippable, hedge branches are clippable, but you wouldn't say a rope is clippable (it's cuttable instead), showing how English speakers unconsciously group items by their texture and rigidity.
