The invention relates to a solar energy collector that comprises at least a cover (11) penetrable by light, an absorber, a system of flow ducts in the absorber, and a frame structure formed of edge profiles (15). The frame structure of the solar energy collector is composed of at least one corner joint, each corner joint comprising at least one insert (17) fitted inside an edge profile (15) and at least one prebent lock pin (18). The inserts (17) are provided with holes (21) for the lock pins (18), said hole (21) including a plane face and said lock pin (18) including a plane face (18a). The joint can be tightened by turning the lock pins (18) such that the plane face (18a) of the lock pins (18) is locked to the plane face of the hole (21) situated in the insert (17). |
