A handle for use with an elastomeric tube in a resistance exercise device is generally U-shaped with a grip removably secured between opposite ends of the handle.

A handle for use with an elastomeric tube in a resistance exercise device is generally U-shaped with a grip removably secured between opposite ends of the handle. A frusto-conical throat is defined through the nadir of the U-shape and receives one end of the tube. A retainer ball of greater diameter than the tube is inserted into one diametrically stretched end of the tube. The diameter of the retainer ball is smaller than the large diameter proximal end of the throat but greater than the small diameter distal end of the throat. With the end of the tube stretched about the retainer ball, the ball compresses the tube wall against the frusto-conical throat wall with a force that increases as the tension in the tube increases (i.e., as the tube is pulled distally). As a result, the tube is prevented from becoming loose and becoming disengaged from the handle during use. Alternatively, a collar may be disposed about the tube distally of the retainer ball to prevent the retainer ball and surrounding tube portion from distally traversing the throat, thereby securing the tube to the handle. In yet another manner, the throat may include various configurations to provide a fitted engagement with the retainer ball and surrounding tube portions. The handle structure is preferably sold as part of a kit, and can be modified so that a second weighted bar, parallel to the weighted grip, can be removably connected between the arms of the U-shaped handle.
