The locking bars have a U-shaped cross section with two legs having side grooves extending over the full length of the legs and limited by a lower web having a thickness of S1 and an upper web having a thickness of S2. The receiving groove has a height H.sub.1 which is greater than the height H.sub.2 of the locking bar by the thickness S1 of the lower web. The receiving groove and the locking bar have a cross-section which is the same in all sections of the closure frame. The receiving groove has an inwardly extending edge strip, which has a height H3 smaller than the height N of the side grooves.
