A cable or the like protection and guide device, which can escape static electricity reliably without an antistatic additive and can minimize the generation of wear particles due to sliding contact is disclosed. A cable or the like protection and guide device according to the present invention includes a number of synthetic resin link bodies (11) articulably connected to each other with a cable or the like (10) inserted therein. Each link body comprises a pair of link plates (21) disposed on both sides of the cable or the like and an inner circumferential side connecting plate (22) and an outer circumferential side connecting plate (23) spanned across a bending inner circumferential side and a bending outer circumferential side of the link plate, respectively. Tongue pieces (41 to 44), which are positioned at the front and rear sides of the longitudinal direction of said protection and guide device and sliding contacts, are provided in a protruded manner on at least one of said inner circumferential side connecting plate and said outer circumferential connecting plate, and a metallic member (50) is incorporated in at least one of sliding contact surfaces (41A to44A) of said tongue pieces.
