  • Patent number: 4712394
    Abstract: An improved arrangement for providing a securing tie point for a long, broad, flat object such as a surfboard. The sleeve may be mounted in a user prepared passage way in the object. The sleeve is basically a hollow cylinder into which a plug is detachably insertable. A securing cable may be passed through the sleeve and around a fixed object to secure the long, broad object. The plug is held in the sleeve with an o-ring. A catch and latch may be used in place of the o-ring. The sleeve may have mounting guides to aid in centering the sleeve in the passage way. The sleeve may be tapered to force the mounting adhesive between the sleeve and the passage way. The plug may contain a leash pin to provide a tie point for a leash between the object and the user. The plug and sleeve may contain a key and guide to aid the proper orientation of the plug into the sleeve. After mounting, the plug and sleeve may be sanded to conform to the surface of the long, broad object.
