Abstract

Abstract A CORD FASTENER OF THE TYPE HAVING A CASING WITH A TUNNEL ADAPTED TO RECEIVE THERETHROUGH TWO CORD PARTS TO BE INTERCONNECTED, A CLAMPING ROLLER FOR THE CORD PARTS MOVABLE LONGITUDINALLY IN THE TUNNEL AND OPERABLE TO CLAMP THE CORDS AGAINST PORTIONS OF SIDE WALLS CLOSER TOGETHER AT ONE END OF THE TUNNEL THAN AT THE OTHER END OF THE TUNNEL WITH A PIN EXTENDING THROUGH A LONGITUDINAL CLOSED END SLOT IN ONE OF THE WIDER WALLS OF THE CASING FOR MANIPULATION TO DISPLACE THE ROLLER FOR CORD-CLAMPING POSITION, THE WIDER WALL HAVING THE SLOT BEING RESILIENTLY FLEXIBLE NORMAL TO ITS PLANE IN LONGITUDINAL ALIGNMENT WITH THE SLOT AND IN THE WIDEST PORTION OF SUCH WIDE WALL TO ENABLE DISPLACEMENT TO PASS THE PIN TO THE SLOT DURING INSERTION AND ASSEMBLY OF THE ROLLER FROM THE ADJACENT END OF THE TUNNEL INTO OPERATIVE RELATION WITHIN THE TUNNEL. A GUIDE GROVE MAY BE PROVIDED IN THE INNER FACE OF THE FLEXIBLE PORTION OF THE WIDER WALL TO FACILITATE PASSAGE OF THE PIN TO THE ASSEMBLED RELATION, AND THE GROOVE MAY BE IN A PORTION OF THE WALL WHICH IS RAISED FROM ITS OUTER SURFACE. THE OPPOSITE WIDER WALL MAY HAVE A RIB ON ITS OUTER FACE ABOUT A LARGE AREA THEREOF. THE NARROW SIDE WALLS MAY BE SHORTER AT THE WIDE END OF THE CASING THUS ENHANCING THE RESILIENCY OF THE RESILIENT PORTION OF THE SLOTTED WALL. THE NARROW WALLS MAY BE SHORTER AT THE NARROW END OF THE CASING TO PROVIDE RECESSES TO RECEIVED THE CORD PARTS IN DIVERGING DIRECTIONS.
