A device for gripping an elongated flexible element, such as a flexible belt, and including a first member, an actuating member mounted to swing relative to the first member between locking and released positions, and a locking member connected to the actuating member for swinging movement therewith and acting in the locking position to clamp the elongated element against a gripping portion of the first member in a relation retaining the elongated element against longitudinal movement, with said locking member being free for limited pivotal movement relative to the actuating member in a relation acting to progressively tighten the grip on said elongated element as a result of said pivotal movement of the locking member relative to the actuating member when the latter is in its locking position.

A buckle comprising: a first member having two generally parallel side walls and having a first crosspiece extending between said side walls at one end thereof and attachable to a first elongated element, and a second crosspiece extending between said side walls at their opposite ends and having a gripping surface facing generally toward said first crosspiece; an actuating member mounted to said first member for relative swinging movement about an axis between a locking position and a released position; said actuating member having an arm which in said locking position is received generally between said two side walls of the first member, and which in said released position swings to a position of extension outwardly from between said side walls; said actuating member having a portion at an end of said arm extending between said side walls and projecting into bearing recesses in the side walls to mount the actuating member for said swinging movement; said last mentioned portion of the actuating member having an outer partial cylindrical surface centered about said axis and interrupted at the location of said arm; and a locking member connected to said actuating member for swinging movement therewith between said locking and released positions and carried about said last mentioned portion of the actuating member for limited pivotal movement relative thereto; said locking member having an internal partial cylindrical bearing surface engaging said outer partial cylindrical surface of the actuating member to mount the locking member for said pivotal movement, and being interrupted at the location of said arm with said arm being disposed within the interruption, the width of the interruption being greater than the corresponding dimension of said arm to permit said limited relative pivotal movement; said locking member having teeth which progressively increase in radius with respect to said axis in a direction progressively gripping a second elongated element more tightly in response to said limited relative movement of the locking member when said actuating member is in said locking position.
