Device consisting of a substantially U-shaped small bar 1 or clip, made of a metal material or the like, which small bar 1 is designed to be introduced into appropriate seats 4 and a groove 5 formed in the ends of blades 2 which are to be assembled and are bevelled at 45 DEG in order to form a frame or a surround. To assemble the two corresponding ends of the blades 2, the two grooves 5 are brought into alignment and the legs 3 of a small bar 1 are force-fitted into the seats 4, thus guaranteeing perfect retention of the assembled parts. <IMAGE>
