The invention concerns an U-shaped linear connector of plastic material for joining box-like hollow spacing profiles of multiple insulating glasses, comprised especially of steel and provided with perforated bottoms. The linear connector is provided at its lateral legs with outwardly directed, inclined, plate-like springs extending in the direction of the longitudinal axis of the connector successively behind one another, and the hollow profiles are provided with a rectangular cross-section and a perforated bottom surface, parallel lateral walls and a roof surface extending parallel ot the bottom surface and having depressed, concavo-convex or rounded, respectively, butyl-receiving flanks between the roof surface and the lateral walls. The U-shaped linear connector is configured such that its fix seat within the hollow space of the profile is even under changing pressure conditions or, respectively, load conditions, caused for instance by thermal tensions maintained. This problem is solved according to the subject invention by the fact that the plate-like springs which are slanting outwardly are precisely ending at the butyl mass receiving edge of the flank and the rounding radius at the abutment of the lateral wall and the roof surface of the hollow profile and thus support the deforming pressure transmitted from the roof surface of the hollow profile to the lateral plate-like springs of the linear connector, avoiding thus the cold deformation of the lateral plate-like springs and in consequence thereof their collapse inwardly under permanent pressure.
