least one covering element (4) fastened to the substructure (2) by at least one latching connection (3), the latching connection (3) being configured as a nondestructively detachable and re-connectable latching connection (3) in order to take the covering element (4) off the substructure (3) and subsequently re-fasten the covering element (4) to the substructure (2). ## Claims ### Claim 1 An arrangement for forming a floor, wall, or ceiling covering, comprising a substructure, at least one covering element fastened to the substructure by a latching connection, the latching connection configured as a nondestructively detachable and re-connectable latching connection in order to allow removal of the at least one covering element from the substructure and subsequent re-fastening of the at least one covering element to the substructure, wherein the latching connection is configured to nondestructively engage the at least one covering element when the at least one covering element is pressed against the substructure in a direction toward the substructure, and nondestructively disengage the at least one covering element when the at least one covering element is lifted from the substructure in a direction perpendicular to and away from the substructure, wherein the latching connection includes at least one latching head and at least one latching receptacle, each of said at least one latching head engaging in a form-fitting manner behind at least one undercut in a respective one of said at least one latching receptacle in an engaged state of the latching connection, wherein the substructure has at least one profile rail in or on which each of said at least one latching head or each of said at least one latching receptacle is arranged, and wherein each of said at least one latching head or each of said at least one latching receptacle is arranged to be displaceable along the profile rail. ### Claim 2 (depends on 1) The arrangement as claimed in claim 1, wherein each said latching receptacle comprises a longitudinally extended groove. ### Claim 3 (depends on 2) The arrangement as claimed in claim 2, wherein each said latching head is shorter than each said latching receptacle in a direction of longitudinal extent of a respective said latching receptacle. ### Claim 4 (depends on 1) The arrangement as claimed in claim 1, wherein at least one of each said latching head or each said latching receptacle has at least one of inclined faces or rounded contours to allow easier engagement, disengagement, or both of the latching connection. ### Claim 5 (depends on 1) The arrangement as claimed in claim 1, wherein at least one of each said latching head or each said latching receptacle are elastically deformable in order to allow engagement, disengagement, or both of the latching connection. ### Claim 6 (depends on 1) The arrangement as claimed in claim 1, wherein at least one of each said latching head or each said latching receptacle have at least regionally, in at least one cross section, a contour which is rounded and extends through an angular range of more than 180°. ### Claim 7 (depends on 6) The arrangement as claimed in claim 6, wherein the contour is circular. ### Claim 8 (depends on 1) The arrangement as claimed in claim 1, wherein the latching connection includes two parts, and in each case one part of at least two of the latching connections is arranged on a common carrier and said ones of the parts of the latching connections are spaced apart from one another. ### Claim 9 (depends on 8) The arrangement as claimed in claim 8, wherein the carrier is arranged in or on a profile rail of the at least one profile rail of the substructure so as to be displaceable along the profile rail. ### Claim 10 (depends on 9) The arrangement as claimed in claim 9, wherein the carrier is arranged in an undercut groove of the at least one profile rail. ### Claim 11 (depends on 8) The arrangement as claimed in claim 8, wherein a compensation region for changing a spacing between said ones of the parts of the latching connections is arranged in the carrier or between the carrier and said ones of the parts of the latching connections. ### Claim 12 (depends on 8) The arrangement as claimed in claim 8, wherein the two parts of the latching connections are latching heads or latching receptacles. ### Claim 13 (depends on 1) The arrangement as claimed in claim 1, wherein each said latching head or each said latching receptacle is arranged on a carrier, wherein at least one pretensioning element is provided on the carrier, wherein each said pretensioning element pretensions the carrier in an undercut groove of the profile rail such that the carrier can be pushed into the undercut groove only counter to a degree of frictional resistance. ### Claim 14 (depends on 13) The arrangement as claimed in claim 13, wherein the pretensioning element is a spring tongue. ### Claim 15 (depends on 11) A method for compensating for changes in at least one of a length or a width of a covering element or an orientation of at least two covering elements relative to one another in an arrangement as claimed in claim 11, the method comprising varying a spacing between the parts of the latching connections in the compensation region. ### Claim 16 (depends on 1) A method for the assembly of a floor, wall, or ceiling covering including the arrangement as claimed in claim 1, the method comprising nondestructively fastening the at least one covering element to the substructure in a detachable manner by engaging the latching connections. ### Claim 17 An arrangement for forming a floor, wall, or ceiling covering, comprising a substructure, at least one covering element fastened to the substructure by a latching connection, the latching connection configured as a nondestructively detachable and re-connectable latching connection in order to allow removal of the at least one covering element from the substructure and subsequent re-fastening of the at least one covering element to the substructure, wherein the latching connection includes at least one latching head and at least one latching receptacle, the at least one latching head engaging in a form-fitting manner behind at least one undercut in the at least one latching receptacle in an engaged state of the latching connection, wherein the substructure has at least one profile rail in or on which the latching head or the latching receptacle is arranged, wherein the at least one latching head or the at least one latching receptacle is arranged to be displaceable along the profile rail, and wherein the at least one latching head or the at least one latching receptacle is arranged on a carrier, wherein at least one pretensioning element is provided on the carrier, wherein the at least one pretensioning element pretensions the carrier in an undercut groove of the profile rail such that the carrier can be pushed into the undercut groove only counter to a degree of frictional resistance.
