(54)	Thermal-break section for door and window frames or the like and associated method for assembling said section

(57) A thermal-break section (21) is described, said section comprising: a first half-shell (22), a second half-shell (23), and at least one body (24) of heat-insulating material, said first half-shell and said second half-shell comprising longitudinal teeth forming a seat for said at least one body of heat-insulating material, characterized in that said first and second half-shells (22,23) comprise at least one fixed longitudinal locating tooth (229,239) and at least one longitudinal tooth (228,238) which can be folded from a first open position into a closed locking position for locking said at least one body (24) of heat-insulating material. The solution according to the present invention can be used for the production of solid and strong thermal-break window and door frames having a thermal-break chamber which is substantially symmetrical and not staggered.
