The pin shaped clamp for clamping together several independent construction parts, such as coffering floors on the top of walls comprises an inverted U shaped spring clamp. The two vertical pin branches (1), widened towards the bottom, are connected by a sliding pin (3) which brings them together when it is lowered. The branches are brought together with the aid of two fixed levers (4), one on each side of the two upper corners of the U. The other ends of the levers are supported on the sliding pin and to push it downwards to provide maximum clamping of the ferrules (2). The upper corners of the U are constituted by loops (5).
