Middle English loupe, probably from Middle Irish lúb (perhaps influenced by Middle English lep, basket).
Middle English loupe; akin to Middle Dutch lūpen, to lie in wait, peer.(American Heritage® Dictionary of the English Language, Fourth Edition)
From Middle English loupe ("noose, loop"), earlier lowp-knot ("loop-knot"), of North Germanic origin, ultimately from Old Norse hlaup ("a run", literally, "a leap"), used in the sense of a "running knot". Compare Swedish löp-knut ("loop-knot"), Danish løb-knude ("a running knot"), Danish løb ("a course"). More at leap. (Wiktionary)
