A support collar for cables, pipes or the like includes a head portion having a pass-through opening; two side portions extending from the head portion and ending with abutment portions disposed substantially parallel to the head portion and with a coupling element adapted to engage the collar onto a support plate or the head portion of another support collar; and retaining members within the housing area for retaining firmly the cable or pipe. The retaining members include a clip having retaining arms that extend inside the housing area and can be elastically splayed to engage the cable or pipe due to an elastic pressure exerted transversely thereon. Each of the retaining arms cooperates with a flap that extends into the housing area opposite of the retaining arms, so that the flap is abutted against the retaining arm when the cable or pipe is engaged in the clip.
