Abstract: A connector for profile sections having axes that intersect at a certain angle (.alpha., .beta.) includes a connecting member folded or cut so that it defines a bearing surface provided with a through-bore and arranged to be attached to any one of the surfaces of a first profile section, the connecting member being pivotable about a first axis parallel or orthogonal to the longitudinal axis of the through-bore, and at least one portion of the member further being pivotable about a second axis orthogonal to the first axis (D1); the part of the connector located beyond a plane parallel to the first axis and passing through the second pivot axis forms an initial attachment portion to which a second profile section is attached either directly or by an insert.
