A one-piece hinge body for pivoting two parallel profiles, the hinge body comprising: - a first profile portion configured to at least partially define an aperture for enclosing a first profile, - a second profile portion configured to at least partially define another aperture for enclosing a second profile parallel to the first profile, - an outer portion connecting the first and second profile portions (130, 140) and being located on the outside of the hinge joint of the pivoted profiles, wherein the outer portion is solid for withstanding retraction upon closing movement of the hinge, and - an inner portion opposing the outer portion, connecting the first and second profile portions (130, 140) and being located on the inside of the hinge joint of the pivoted profiles, wherein the inner portion consists of joinable terminal ends (150, 160) of the first and second profile portions (130, 140), wherein a mating surface is formed between said joined terminal ends (150, 160), characterized in that, - one of the terminal ends comprises an extension which is adapted to engage with the inner surface of the outer portion and shaped to partially define apertures (170, 180) for enclosing the profiles, wherein the body comprises two parallel apertures (170, 180) for receiving the profiles, the apertures (170, 180) being separated by the extension of said either terminal end, - the other terminal end is adapted to close the body by coupling to the terminal end comprising said extension, and wherein - the terminal ends (150, 160) comprise corresponding holes (153, 163), which: • are parallel to the apertures (170, 180) for the profiles and which • are aligned when the body is in closed position, i.e. the terminal ends (150, 160) are joined, and which • may be secured to each other by means of a torsion bar inserted through the consecutive holes (153, 163) of the terminal ends (150, 160). - a first profile portion configured to at least partially define an aperture for enclosing a first profile, - a second profile portion configured to at least partially define another aperture for enclosing a second profile parallel to the first profile, - an outer portion connecting the first and second profile portions (130, 140) and being located on the outside of the hinge joint of the pivoted profiles, wherein the outer portion is solid for withstanding retraction upon closing movement of the hinge, and - an inner portion opposing the outer portion, connecting the first and second profile portions (130, 140) and being located on the inside of the hinge joint of the pivoted profiles, wherein the inner portion consists of joinable terminal ends (150, 160) of the first and second profile portions (130, 140), wherein a mating surface is formed between said joined terminal ends (150, 160), characterized in that, - one of the terminal ends comprises an extension which is adapted to engage with the inner surface of the outer portion and shaped to partially define apertures (170, 180) for enclosing the profiles, wherein the body comprises two parallel apertures (170, 180) for receiving the profiles, the apertures (170, 180) being separated by the extension of said either terminal end, - the other terminal end is adapted to close the body by coupling to the terminal end comprising said extension, and wherein - the terminal ends (150, 160) comprise corresponding holes (153, 163), which: • are parallel to the apertures (170, 180) for the profiles and which • are aligned when the body is in closed position, i.e. the terminal ends (150, 160) are joined, and which • may be secured to each other by means of a torsion bar inserted through the consecutive holes (153, 163) of the terminal ends (150, 160). • are parallel to the apertures (170, 180) for the profiles and which • are aligned when the body is in closed position, i.e. the terminal ends (150, 160) are joined, and which • may be secured to each other by means of a torsion bar inserted through the consecutive holes (153, 163) of the terminal ends (150, 160).
