Claim 1
Independent Claim
136 words
An apparatus for releasably attaching risers of a parachute from a harness of the parachutist and adapted to permit release of the parachute while said parachutist is in mid-air comprising a ring member attached to the harness of the parachutist; and a series of loops, each directly attached to a respective set of said risers, a first loop in the series being insertable through said ring member on said harness, and each additional loop being insertable through the preceeding loop in the series; and a flexible thong turned around the last loop in said series and through a rip cord assembly with a rip cord inserted into an aperture in said thong for releasably securing the last loop in said series and maintaining said loops in contact one with the other when in a secure position.
