A sheathed endoscope has a flexible elongate insert part and a sheath that is removably fitted over the insert part. The sheathed endoscope comprises a distal end part that is provided at the distal end of the insert part, a distal end cover that is provided at the distal end of the sheath and that is removably fitted over the distal end part, and a lock device that is provided on the distal end cover so as to be engageable with the distal end part. The lock device is disengaged from the distal end part by deforming the distal end cover so that the lock device moves radially outward. A sheath for a sheathed endoscope is provided and is removably fitted over a flexible elongate insert part of the endoscope. The sheath comprises a flexible tubular member that is removably fitted over the insert part, a distal end cover that is connected to the distal end of the tubular member so as to be removably fitted over the distal end of the insert part, the cover being made of a shape-memory synthetic resin material that is restored to a previously memorized shape by heating it to a shape restoration temperature, and a lock device that is provided on the distal end cover.
