A holder for rod-like objects, such as pipes, cables or the like, has a holder portion and a slide which is pressed longitudinally into the holder portion. The holder portion has a pair of arms forming a trough into which the rod-like object is placed. The slide, forming an extension of the trough, has retaining elements that are moved by a wedging action when the slide is pushed into the holding portion, so as to contact the rod-like object to maintain its position on the holder.
