Abstract: An overcenter clamp comprises a flexible band having a hinge end and a hooked end. The hooked end is adapted to grasp a margin of a first member. The overcenter clamp further comprises a lever arm hingedly connected to the hinge end. The lever arm has a handle and a pivot link. The pivot link has an end adapted for insertion into a socket in a second member. This enables the first and second members to be clamped together by grasping the margin with the hooked end, inserting the pivot link into the socket, and rotating the handle away from the band to a point wherein the band is tensioned and bears upon the second member. The overcenter clamp includes a retainer connected to the band adjacent the hinge end. The retainer is engageable with the lever arm to resist rotation of the lever arm with respect to the band when the lever arm is in an open position wherein the angle between the lever arm and band is sufficient so that, when the hooked end grasps the margin, the pivot link is away from the socket.
