fitting groove 5 u2032 and the feather key 15 u2032 in a wedge shape or conically in the direction of the side edges 2 u2032 3 u2032 the panel 1 u2033 illustrated in fig6 to 9 is similar to the panel 1 1 u2032 according to fig1 to 5 and therefore the same elements also bear the same reference numerals and the same principles apply when coupling as well as separating such panels 1 1 u2032 1 u2033 the first locking nose 8 u2033 of the first side edge 2 u2033 is arranged on a locking lip 12 u2033 which on the one hand is provided on a locking element 6 u2033 and on the other hand adjoins an elasticity groove 13 u2033 the elasticity groove 13 u2033 and the locking lip 12 u2033 ensure that when coupling the first and second side edges 2 u2033 3 u2033 the second locking nose 11 u2033 can pass the first locking nose 8 u2033 without causing any damage in the case of the panel 1 u2033 illustrated and to this extent preferred in fig6 to 9 the elasticity groove 13 u2033 is filled with an elastic composition for example in the form of an adhesive the elasticity groove 13 u2033 need however not be completely filled and also not only with an elastic composition at least one elastic composition can be provided in a similar way in the elasticity groove 13 also in a panel 1 1 u2032 according to fig1 to 5 the elasticity groove 13 illustrated in fig1 to 5 can however also be dispensed with also in the panel illustrated and to this extent preferred.
