Abstract: A flexible over-center draw latch is disclosed which is adapted for securing together two closure members. The latch comprises a keeper mounted on the one closure member and a latch assembly mounted on the other closure member. The latch assembly includes a base which is adapted to be mounted on the second closure member, a substantially elastic latch body pivotally connected to the base and a lever which is pivotally connected to the latch body.
