Abstract: An anchor plug with a leash pin is mounted in a surfboard by drilling a hole in the top surface of the board, pouring resin into the hole, inserting the anchor plug so that it is substantially flush with the surfboard surface, causing the resin to harden, and then abrading away the closed top of the anchor plug to expose a cavity with a leash pin within it. The leash pin may be moved between a holding and a release position by pushing down on an actuator and sliding it in an actuator cavity. The anchor plug may be mounted in a Boogie Board by providing a stem with external threading extending from the bottom of the plug, and having it cooperate with a locking element having an internally threaded projection.

Abstract: An improved anchor plug allowing quick release of a leash. The anchor plug is preferably made of plastic and may be mounted on a surfboard, or any other object flush to the top surface of the surfboard. The anchor plug has a leash cavity and a retractable leash pin spanning the leash cavity. Preferably, the leash pin extends into a locking hole when it is in the extended position. A loop can be formed in a leash, the leash pin can be retracted to allow the loop to be inserted in the leash cavity, and the pin can be extended to retain the loop in the leash cavity. Preferably, the leash pin is made of stainless steel and can be locked in the extended position.
