A hose or cable protector has a pair of articulating guides, each with rollers for creating an arcuate hose path around the sharp corner of a tunnel mouth which would otherwise cause abrasion to the hose. A stop imposes a guide to guide angle of eighty (80) degrees but the usual angle is greater and up to one hundred and twenty (120) degrees. Arches span the guides and retain the protector on the hose or cable. In a variant, the arches are spring loaded and adjustable to retain or release the hose. A control line positions the protector at the selected site.
