Device for maintaining stretched a panel of supple material, by its edges

Device for fixing on a support (2) such as a ceiling and stretching by its edges a panel (3) of supple material, of the type comprising:

• an elongate section (6) having opposing distal and proximal lateral edges extending along the length of said section and capable of being fixed on said support (2);
• a substantially elongated element (7) having opposing distal and proximal lateral edges extending along the length of said element of which said distal comprises means for blocking said panel (3) and of which said proximal edge (23) is adapted to pivotally cooperate in abutment with a first housing (24) of complementary dimension and shape provided on said section (6), the element (7) being independent of the section (6);
• means for removably connecting the element (7) on said section 6, in order to maintain the element (7) in an operative sheet holding place on the section (6);
• characterized in that said connecting means are disposed towards said distal edges of said section and said element and are adapted to immobilize the element (7) on the section in all directions and independently of said means for blocking of the panel on the element, and in that said means for blocking the panel (3) are provided in said distal edge of said element (7), are of the pinching type and are constituted by a deformable lip (20) associated with a second housing (19), both being capable of being spaced apart, to allow passage of the edge of the panel (3) in the housing (19), said lip (20) being previously moved apart and capable of returning, by its own elasticity, into its original position, where it bears, by its deformable lip, against the edge (13) of the second housing (19) and thus blocks by pinching the edge of the panel (3).
