1. A snare for an endoscope comprising:

  • a flexible sheath;

    a control wire axially movably inserted in said flexible sheath; and

    a snare wire connected to a distal end of said control wire, said snare wire being formed from an elastic wire;

    wherein when said control wire is advanced axially, said snare wire projects from a distal end of said flexible sheath and expands in a loop shape by its own elasticity, whereas when said control wire is retracted axially, said snare wire is pulled into the distal end of said flexible sheath and thus contracted;

    wherein a distal end surface of said flexible sheath is provided with a plurality of claw-shaped projections projecting forward in parallel to each other.
