Abstract
The utility model discloses a protective clamping sleeve which has axial bore. A contraction groove is arranged on the sidewall of the axial bore, and a circumferential slot is arranged on the central section at the outer side of the protective clamping sleeve. The protective clamping sleeve, when subjected to a radial force, contracts radially so that two side surfaces of the contraction groove approach to each other or are attached together. The circumferential length of the protective clamping sleeve is reduced, so that the protective clamping sleeve can be inserted in a through hole in a metallic plate. When the radial force disappears, the structure of the protective clamping sleeve is restored, so that the circumferential slot of the protective clamping sleeve is tightly stuck in the through hole in a metallic plate. A pipe may pass through the axial bore of the protective clamping sleeve, thereby protecting the pipe from being scratched by the metallic plate. The protective clamping sleeve is convenient to install and can be inserted into and stuck in the through hole in a metallic plate by hand. The protective clamping sleeve also can be pulled out of the through hole in a metallic plate by hand.
