An end portion of an elongate member of generally cylindrical form, such as an optical fiber, is placed in a predetermined position utilizing a substrate having a surface that is defined by a generatrix that is a straight line, e.g. a flat surface. A foil of flexible material is secured to the surface of the substrate and defines with the substrate a generally straight, elongate passageway that is parallel to the generatrix of the surface and has a first portion of substantially uniform cross-section adapted to receive an end of the elongate member in closely fitting relationship and also has a second portion that tapers towards the first portion. The end portion of the elongate member is inserted into the first portion of the passageway by way of the second portion thereof.
