Abstract: A mounting frame (100) which can be attached to a ceiling (3) and comprises an assembly of basic profiles (10) comprising a housing (14) for receiving an edge of a covering (1) and a plurality of V-shaped or U-shaped locking clips (50) designed to enter the receiving housing (14) and remain therein in a locked position in which the edge of the covering (1) is clamped between the locking clip (50) and the housing (14). Each locking clip (50) is interposed between an insertion tool and the covering (1) and facilitates the insertion of the covering (1) into the receiving housing (14) without damaging the covering (1). The covering (1), with dimensions greater than those of the frame, can thus be completely removed and reused since the covering has not been damaged in any way, either while the covering (1) is being fitted or while being held in place.
