Abstract: This invention relates to a flexible line fastener device for securely holding flexible lines to stationary objects such as poles and the like, in particular. This device comprises an elongated plate-like base contoured to fit securely about a pole as such; a grommet disposed on a front surface of the base near a top end thereof for anchoring flexible lines removably fastened to the device; a plurality of elongated cleats longitudinally integral to the base and arranged at acute angles to the axes of the base and each having a V-shaped end to effectively grip a flexible line wound through and about the cleats; and a clasp member disposed near the top end of the base to effectively secure the flexible line in the cleats.
