A protective sheath for an endoscope probe comprises a pair of elongated plastic sheets peripherally sealed together at the sides and distal ends thereof, while being unsealed at the proximal ends. A first of the sheets is transparent, having greater optical clarity than the other sheet. The other sheet has better frictional slip characteristics than the first sheath. Also, an intermediate plastic sheet may be provided between the pair of plastic sheets, so that the endoscope probe slides into the sheath between the other sheet and the intermediate sheet. The intermediate plastic sheet may have better frictional slip characteristics than the first sheet, to render easier the advancement of the probe into the sheath. The intermediate sheet terminates short of the distal ends of the sheet pair.
