Abstract: An elastic resistance exercise device is described which comprises an elongated elastic member having a handle attached at each end by friction-lock components. A disassemblable bar member is used coactively with the elastic member or with the handles by sliding the bar in and through hollow cylinders operatively attached to the handles. The handles provide adjustable detachability of the elastic member by the coaction of receptacles defined therein through which the elastic member is slidably fit and frictionally retained. In one handle, a solid plug is frictionally inserted in the elastic member and at the other handle, an adjustable member attached to a pull handle frictionally bears upon the elastic member and secures it in the handle. The device can be assembled into a small compact mass to facilitate transport in a briefcase or the like when traveling.
