(54)	Thermally insulating body for a thermal break section for window and door frames or the like

(57) What is described is a longitudinally extending thermally insulating bar-like body (11) for making metal thermal-break sections. The body has a cross-section comprising a stem (12) and two enlarged end heads (13). The heads (13) are provided substantially at the respective ends of the stem (12). The heads have a profile, in cross section, substantially in the form of a trapezium with its longer base forming a first support surface (13d) for engaging with a corresponding bottom surface of a recess for the said thermally insulating body and with its inclined sides for engaging with longitudinal inclined retaining teeth or longitudinal shoulders of metal half-shells. According to the invention, the body further comprises a first male member (15b) and a corresponding first female member (15a) that are suitable to mate with a female member and a male member, respectively, of a further thermally insulating body in order to form a substantially tubular-like thermally insulating body.
