A support strip (FIG. 2) of plastic material with U-shaped cross-section and for supporting conduits, cables etc. has a substantially plane bottom (2) and side walls (3), which support strip (1) in its bottom surface close to the longitudinal edges of the support strip has a groove (5) extending along the entire length of the support strip with opposed grip edges (6,7). The free outer edge of each side wall (3) is formed along its entire length with a substantially cylindric bead (8), the diameter of which is slightly smaller than the width of the groove (5) and greater than the distance between the grip edges. Both beads (8) are located at the same distance from the bottom (2) and in a plane (x) extending perpendicularly to the bottom and in the central longitudinal line of the respective groove. The support strip (1) further comprises two internal support walls (10) spaced from each other and in parallel with the side walls (3), which support walls (10) at their outer end are formed with stop strips (11) for retaining conduits, cables etc. placed in the support strip. The mutual distance between the grooves (5) and, respectively, beads (8) of the support strips is equal, so that two or more support strips can be coupled together, in that the beads (8) of one support strip are pressed into the grooves (5) of the other support strip whereby a snap connection between the support strips is formed.
