A pipeline bundling assembly for holding a first pipeline and a second pipeline parallel at a distance from each other, comprising a basic element and a covering element, which basic element comprises a first enveloping side for partly enveloping the first pipeline in circumferential direction of the first pipeline, and a second enveloping side located opposite the first enveloping side for partly enveloping the second pipeline in circumferential direction of the second pipeline, and which covering element comprises a third enveloping side for partly enveloping the second pipeline in circumferential direction of the second pipeline, wherein the covering element can be brought into a covering condition connected with the basic element by interlocking therewith, in which covering condition the basic element and the covering element face each other by the second enveloping side and the third enveloping side, respectively, and wherein the assembly can take an operative condition, in which operative condition said first pipeline and said second pipeline are held parallel at a distance from each other in that the covering element is in said covering condition and the first pipeline is partly enveloped by the first enveloping side, and the second pipeline is partly enveloped by the second enveloping side and is partly enveloped by the third enveloping side, wherein the basic element and the covering element comprise mutually cooperating snap connection elements (4, 5) for bringing the covering element in said covering condition by means of snap connection and maintaining the covering condition in said operative condition of the assembly, characterized in that the assembly is designed to permit the covering element to be brought, as desired, from at least two different placement conditions of the covering element relative to the basic element, by means of said snap connection, into said covering condition, which is realised in that a first outer surface structure of the basic element and a second outer surface structure of the covering element on sides of the basic element and of the covering element facing each other in the covering condition are each provided with at least one elevation (42, 43) and at least one recess (52, 53), which first outer surface structure and second outer surface structure in said covering condition, through different mutual orientations of the basic element and the covering element, can, as desired, abut against each other in different manners such that: - the elevation of the first outer surface structure abuts against the elevation of the second outer surface structure, in which case a first placement condition of said placement conditions occurs, or - the elevation of the first outer surface structure abuts against the recess of the second outer surface structure, in which case a second placement condition of said placement conditions occurs, wherein, in the first placement condition and in the second placement condition, respectively, a first intermediate space between the second enveloping side and the third enveloping side, and a second intermediate space between the second enveloping side and the third enveloping side are defined in a condition in which the covering element in the respective placement condition is pressed as far as possible in the direction towards the basic element against the basic element, and wherein said first intermediate space in the first placement condition is greater than said second intermediate space in the second placement condition. - the elevation of the first outer surface structure abuts against the elevation of the second outer surface structure, in which case a first placement condition of said placement conditions occurs, or - the elevation of the first outer surface structure abuts against the recess of the second outer surface structure, in which case a second placement condition of said placement conditions occurs,
