A harness plate comprising a plate portion for secure attachment to a harness back plate for supporting a wearer from a support line is formed on one side with a toroidal passage centered midway between sides of the plate portion and open at one end facing an upper edge of the plate. A shackle staple is secured to the plate portion and has a pair of upwardly extending arms with opposed apertures through which passes the free end of a toroidal shackle pin telescopically mounted in the passage and biased through the arm apertures by a compression spring compressible to allow manual movement of the free end of the pin from between the arms. The eye of a suspension rope may be positioned between the arms and secured by the pin to the plate so that support rope tension can be conveyed to the back panel in secure manner. On release of tension the connection is readily released by manual compression of the spring through a finger lever on an exposed portion of the pin. The toroidal passage is of open channel form, closed by a removable cover plate.
