ABSTRACT OF THE DISCLOSURE A draw clamp for holding together abutting portions of a frame for facilitating joining of the portions to one another has a base member provided with a pair of planar support surfaces extending into the base member toward one another and meeting at substantially a right angle to form a cradle for the frame portions. Pivotally mounted on the base member is a handle which actuates a pair of locking jaws also pivotally mounted on the base member and terminating in double fangs arranged for selectively gripping the frame portions being supported by the cradle. The pivotal mounting for the handle includes an elongated slot in the base member for reception of a pivot pin therethrough. A washer is also provided between the adjacent surfaces of the base member and the handle member. This structure forms a clutch-lock type arrangement. The handle is connected to the locking jaws by a pair of links, each one of which is pivotally connected to the handle and to an arm of an associated locking jaw which extends from a pivot point of the locking jaw in a direction substantially opposite to the direction of an arm which terminates in the associated double fangs. A protrusion on the handle member together with the special shape of the handle forms a portion for engagement by an operator's hand in a non-slip manner.
