An integral, one piece molded coupler includes an inner member and a pair of surrounding half sleeves joined to each other and to the inner member by an integral H-shaped hinge. The half sleeve members are elastically pivotable about the molded hinge members with respect to the inner sleeve. The molded hinge members are elastically deformable and provide a clamping force which maintains the coupling engagement of the coupler.
