Abstract: A multi-contact electrical connector having a plug section and a receptacle section is provided with a breech lock for releasably securing the separate sections of the connector together. Toggle action biasing means such as a conical disc spring and high lead threads with a predetermined amount of lost motion therein insure a "snap-action" mating and unmating of the two sections and the parts thereof as the breech lock is set and unset. This prevents a "false mating" and insures that the connector will always be either fully and completely mated or unmated. A short pin or remote mate monitor contact is included whereby the condition of the connector can be automatically and/or remotely monitored.

Abstract: A parachute riser buckle is provided on the parachute harness for a quick release of the parachute risers from the harness. Blocking means on the buckle body has a latch position in which it blocks removal of the riser connecting portion and an unlatched position for permitting removal of the riser connecting portion. A latch preventing member is provided which has a position in which it prevents the blocking means from returning to its latched position from its unlatched position except when the riser connecting portion is inserted in the buckle body to prevent incorrect and non-positive latching of the blocking means with the riser connecting portion. A handle is provided to rotate with the blocking means and has a surface which prevents the latch preventing member from moving to its latch preventing position except when the handle moves the blocking member to its unlatched position.
