    Abstract: A jewelry clasp is provided with a female member and a complementary male member adapted to cooperate with a releasable locking member disposed within the body of the female member, where the locking member engages the male member to hold the male member within the female member to prevent removal thereof. The locking member includes an integral one-piece construction having a locking portion for engaging the male member, a resilient portion for biassing the locking portion against the male member, and an actuating portion for moving the locking portion relative to the pressure of the resilient portion for releasing the male member to permit retraction of the male member from the female member.
