A pre-assembly connector (14) bored for the fixer screw (7) shaft (6) is inserted in the cover strip (11) holes (13) so the connector head (15) rests on the strip (11) and the anchoring foot (16) of the connector can be latched directly or indirectly to the frame posts of the beam. The head is twistably mounted in a recess in the strip (11) and is designed as a plate as wide as the groove containing it in the strip (11). The plate itself is channeled centrally for the fixer screw (7), the channel itself passing right through the connector (14). The plate is also recessed for material economy and the inside diameter of the plate channel is less than the outside diameter of the screw thread so that the inserted screw (7) parts head (15) from foot (16).
