ABSTRACT:
A detachable retainer for optical fibers, in particular optical fiber ribbons, is intended to be used in welding operations. The retainer generally has the structure of a rectangular block having lids that can be swung up and down and are arranged at the top side of the block for clamping the optical fibers. On the underside of the retainer a cylindrical recess is provided, along the transversal diameter of which a more shallow groove is provided which extends up to the longitudinal sides of the retainer. The corresponding flat surface, where the retainer is to be placed, has a cylindrical, short projection or boss having an upper edge with a large bevel and a transversal pin or transversal rib. The pin or rib has a close or tight fit to the corresponding groove in the underside of the retainer whereas the boss and the cylindrical recess have a fit with a considerable play. This results in that the retainer can be easily placed at its position by the boss and the cylindrical recess guiding the retainer to an approximate position and then a more accurate position in the longitudinal direction is obtained, when the pin or the is rib enters the groove. A limited movability is obtained in the lateral direction, which can be required in the case where the optical fibers are to be fitted into stationary V-grooves.
