A pulley is connected with the central portion of the cross strap. A cord is connected with a first handle-stirrup, thence reeved about the pulley and thence connected with a cord connector and at a location intermediate the length of the cord. The cord connector is connected with a second handle-stirrup. The connection between the cord connector and the cord is characterized by free sliding movement during one direction of relative travel therebetween and releasable, positive stop, connection during relative travel in the other direction. A form of such connector includes a ball check cooperating with the tapered conical enclosure.
