• Lowering can be connected to each other, this means that a panel 2a can be held parallel to the already installed panel 2 and lowered for the purpose of connecting, while the lowering the parallel position can be maintained, panel 2a has been lowered so far that it is in the same plane as the panel 2, then there is a downwardly projecting nose 14 in an upwardly open recess 6, parallel to the surface 9 and perpendicular to the joint, the panels 2 and 2a are then interlocked by positive locking, that at the end of the lower protruding lip 5, the locking element directed upwards is then bent slightly outwards, which can in particular be favored by a bevel 90, which is advantageously located below the locking element,
• a gap of, for example, 2.5 mm remains on the surface 9 of the panels 2, 2a. If a cord-like element of, for example, 2.2 mm width is now placed in this gap, this is possible without any problem, since there is play After inserting the cord-like element, panel 2 is pushed approx. 0.5 mm in the direction of panel 2, so that the spring 1 2, which is relatively short here, gets into the groove 3 and thus a lock is obtained vertically to the surface 9, this displacement movement of a few 10th mm is used to bring the cord-like element pressed between the joint that is provided on the surface 9,

• FIG. 21 shows an embodiment of the invention, which is to be preferred if only a rod-like or cord-like element 18 is brought between two panels 1 and 2 from the top 9, if the cord-like element is not between the two panels 1 and 2 in brought as shown, so are the two
• the panels 1 and 2 shown in FIG. 21 are designed in such a way that a gap remains at the top of the joint 1 1.
• the gap is preferably somewhat less wide (a few tenths of a millimeter) than the rod-like or cord-like element 1 8 rod-like or cord-like element pressed into the gap from above, this then comes slightly compressed into the gap. This ensures that the top is sealed watertight. Moisture problems are avoided
• the gap shown in FIG. 21 extends to the top of the spring 1 2, Aus This is expedient for manufacturing reasons, but is not necessary for carrying out the invention,
• a rod-like or cord-like element 18, as can be used in the panels 1 and 2 shown in FIG. 21, is shown in section in FIGS. 22 and 23. It has at least one preferably two recesses 96 on the side, the recesses 96 cooperate with the protruding lugs 95 in such a way that the desired form fit is achieved,
• Element 1 8 on two legs, which can be easily pressed together sufficiently. It is then particularly easy to press the rod-like or cord-like element 1 8 into the gap provided at the joint 1 1,
• the rod-like or cord-like element 18 tapers like a funnel on the underside.
• the correspondingly inclined surface areas 98 ensure that the st ⁇ b- or cord-like element 1 8 can be easily brought into the gap,

• FIG. 23 The embodiment shown in FIG. 23 is preferred. Here there is an upper region 99 of rod-like or cord-like
• the area made of harder material particularly well ensures the proper, reliable fit of a rod - or cord-like element between two panels 1 and 2, the part consisting of a relatively soft area 99 ensures that the rod-like or cord-like element 1 8 can also be pressed together here, thus ensuring that the rod-like or cord-like element 1 8 can get completely into the gap between two panels 1 and 2, even if it is somewhat narrower.
• the upper region 99 is then advantageously lightly pressed between the two panels in order to protect against the ingress of moisture, dust, etc.
