ABSTRACT:
A spine for flexible aquarium air hoses includes a plurality of rib members, each having at least three radially disposed ribs, and each adjacent pair of rib members are connected at the centers by a substantially flexible connecting member. The spine is inserted inside the flexible hose at areas where the hose is to be bent, thereby preventing kinking of the hose.
