A rope locking device which cooperates with the yoke on an archery wrist strap is used to lock a rope which connects an archery release with the wrist strap. The locking device includes a generally cylindrical body portion having a longitudinal axis and a contoured outer surface. At one end of the body portion is a head portion containing a pair of openings for receiving the rope. The rope passes through the openings and along the contoured outer surface of the locking device body portion. When the locking device is wedged into an opening in the yoke, the rope is cinched between the locking device and the yoke to lock the rope in place.
