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.

A device comprising: a body past which two elongated flexible elements can extend; an actuating member mounted to said body for relative swinging movement essentially about an axis between a locking position and a released position; and two locking members for engaging said two elongated flexible elements respectively and retaining them against longitudinal movement in a predetermined direction and which are connected to said actuating member for swinging movement therewith between said positions; each of said locking members having a gripping portion which in said locking position of the actuating member is positioned to clamp a corresponding one of said elongated elements against said body, and which in said released position of the actuating member releases said corresponding element for longitudinal movement in said direction; means mounting each of said locking members for limited pivotal movement about said axis relative to said actuating member and relative to the other of said locking members when the actuating member is in said locking position thereof; said gripping portion of each of said locking members being constructed to grip the corresponding one of said elongated flexible elements progressively more tightly as that locking member pivots relative to the actuating members and relative to the other of said locking members when t e actuating member is in said locking position.
