Abstract: This removable snap-on plastic device can be affixed to a surfboard leash allowing the open outer sleeve portion to clamp onto any adjacent section of the leash to prevent it from unraveling, representing significant improvements over other similar devices. This device does not interfere with the performance of a surfer nor affect the performance of the surfboard leash.

Abstract: This removable snap-on plastic cylinder with a half pipe barrel molded parallel can be affixed to a surfboard leash or any power cord, rope, etc., allowing the open barrel side to clamp onto any adjacent section of the leash or cord to prevent it from unraveling. This device represents significant improvements over other similar devices. This device does not interfere with the performance of a surfer and does not affect the performance of the surfboard leash.

Abstract: A battery for use with a modular battery assembly is provided. The battery includes two poles, with each pole including a dual terminal. Each dual terminal includes a first connector and a second connector. The battery is adapted to be mounted in either of a first housing, with a wiring board having a prewired circuit located thereon connected to slide-in terminals arranged on the wiring board, and a second housing without a prewired circuit. The slide-in terminals arranged on the wiring board are adapted to be located in complementary positions to the first connectors on the battery such that when the battery is slidably received in the first housing, the first connectors are adapted to be received in the complementarily positioned slide-in terminals, and when the battery is located in the second housing, the second connectors are connectable using jumpers such that the battery is adapted to be used interchangeably in the first and second housings.
