A mobile plate (4) bears a straight sliding clamp (6), returned by a spring and a rotary clamp (7), adapted each to engage one of the two mouldings to be stapled. The sliding clamp (6) is fixed to a jib (8) which extends beneath the mobile plate (4). The rotary clamp (7) is integral with a spindle (9) passing through the mobile plate and which bears in its lower part a lever (10) extending towards the jib (8) whereto it is fixed by an anchoring pin (11). The invention is applicable to frame assembling.
