A detachable fin is secured to a socket imbedded into the bottom layer of a watercraft such as a surfboard, wind surf board, standup paddle board, or kayak for example, by a mechanism including a screw whose head which is captured into a slot in the socket, and which passes through a hole in a spur projecting from the portion of the fin inserted into the slot. Two pivotally joined arms engaged over the screw astride a nut and forming a surrounding sleeve. The arms are locked in place by a padlock hasp, preventing the unauthorized extraction of the fin and a situs for locking to a cable or chain for securing the board.
