ABSTRACT:
A cable protection and guide device includes an engagement mechanism for securing connecting plates in a bridged arrangement over flexional inner and outer circumferential sides of side plates of the device. The connecting plates are not inadvertently disengaged because the engagement mechanism includes several features for securing the connecting plates to the side plates. The connecting plate engagement mechanism has a louver body and a louver type connecting plate which pivots about a pair of right and left supporting shafts which are formed at both ends of the louver type connecting plate. The louver type connecting plate is attachably fitted onto the pair of right and left side plates.
