Disclosed is a device for clamping two plates with their surfaces laid on each other, comprising a hollow head, a hollow trunk provided on each side with a side catch and provided with a tongue between its opposite sides, a leg extension hinged to the trunk and provided with a front catch, and a foot integrally connected to the end of the leg extension. In use, the leg extension is folded to fit in the trunk hollow space, and at the same time, the foot is pushed in the head hollow space. The folded body is pushed in a fixing aperture made in a first plate until its side catches engage the undersurface of the aperture edge. Then, the first plate is pushed against a second plate with the folded clamp inserted in a fixing aperture made in the second plate until its front catch engages the undersurface of the aperture edge of the second plate. In unclamping, the foot is pushed against the resilient tongue to disengage the front catch from the underlying plate, and then the overlying plate can be readily detached from the underlying plate.
