A device for retaining two cords, which may be opposite ends of a single cord, against longitudinal movement in a predetermined direction, and including an actuating member connected to a body for pivotal movement between locking and released positions, and two separate locking members carried by the actuating member for pivotal movement therewith and engaging the two cords respectively to retain them against movement. Each of the locking members is also free for pivotal movement relative to the actuating member and relative to the other locking member in a manner automatically tightening the grip on the corresponding cord in response to the application of longitudinal pulling force to the cord. The actuating member and locking members are connected to the body of the device by a pivot pin which extends between two side walls of the body and through a tubular mounting portion of the actuating member and is preferably retained in assembled position by a snap detent arrangement. |
