Abstract: The invention relates to a device (D) for locking/unlocking to the ground (S) of a connecting plate (100) to the ground or to the rim of a basin of a roof element, the plate (100) being on the one hand connected to the rim of the roof element and on the other hand connected to the ground (S) or to the basin rim, the plate (100) being pierced with an orifice (121) coming opposite a hole (200) made in the ground, the locking/unlocking device interacting with the hole (200) made in the ground and resting on the plate (100) for the purpose of attaching the latter. This device is noteworthy in that it comprises an expandable bush (300) changing from a volume called a rest volume allowing it to be inserted into the hole (200) made in the ground to a volume called the expanded volume ensuring its adhesion to the walls (210) of the said hole (200). Applications: attaching swimming pool shelters.

Abstract: The invention relates to a shelter (A) for, for example, a pool- or spa-type recreational basin (B) that is formed of roofing elements (I) and is capable of passing from a deployed position, where the roofing elements are placed in a juxtaposed manner and the basin is covered, to a stacked position, where the roofing elements are placed one over the other and the basin is partially or completely uncovered, said roofing elements (I) including two transverse sections (110 and 120) cross-tied with longitudinal cross-pieces (130), with the so-called extreme cross-pieces (140 and 150) placed on the ends of said sections (110 and 120) that eventually rest on the rim of the basin (B) through a rolling means (300) that is formed of wheels (310) and remarkable in that the wheels (310) are mounted on wheel holders (320) that are foldably mounted relative to the extreme cross-pieces (140 and 150) so as to enable the folding away thereof during the stacking of the roofing elements (I).
