A clamp is for clamping a first member to a second member. The clamp comprises a lever that is rotatably coupled to the first member and a plunger. The lever comprises a handle and a cam that rotate together about a rotational axis. Rotation of the lever about the axis in a first direction cams the plunger towards the second member to couple the first and second members together and wherein rotation of the lever about the axis in a second, opposite direction cams the plunger away from the second member to uncouple the first and second members from each other.
