Abstract (en)
[origin: EP3730732A1] Plug-in joining member (1) designed to make connections between ends of window frame profiles is formed as an elongated piece with nearly U-shaped cross-section and comprising a bottom wall (2) and side walls (3) adjacent to the bottom wall (2) down its side edges. Side walls (3) of the joining member (1) are provided with friction claws (4), arranged at the both sides of the central line (O) and turned towards the central line (O) of the joining member (1). The joining member (1) also has at least one central stop (5, 5'). Cam radiuses R<sub>1</sub>, R<sub>2</sub>, R<sub>3</sub>, R<sub>4</sub>in working portions (4A) of each subsequent friction claw (4) on a specific side wall (3) gradually increase from each far end of the joining member (1) towards the central line (O) of the joining member (1), whereas tips (7) of working portions (4A) of friction claws (4), after having them bent out to working positions, are arranged at the same elevations above the bottom wall (2).Preferably, uniform stiffness of all friction claws (4) is maintained and tips (7) of working portions (4A) of friction claws extend outwardly to the same distance with reference to the longitudinal central axis (O<sub>1</sub>) of the joining member (1).
