Claim:
A safing lock, comprising: an elongate casing perforated by an axial bore partially obstructed by radially extending surfaces, said bore bearing axially extending flutes leading into a circumferentially extending chamber; a bolt rotatably received within said bore, said bolt positioning at a proximal end of said axial bore, the bolt having a key port bearing sets of peripheral slots oriented to retentively receive radially extending teeth of a key inserted into said port, and the key port bearing radially protruding detents axially reciprocating within said flutes and rotationally traversing said chamber upon rotation of said bolt by the key; an interlocking element borne by a distal end of said bolt with a disposition to operatively engage an arming device; and a resilient element located within said bore between said bore and said bolt amenable to compression as said bolt is forced axially against said resilient element and said detents travel axially along said flutes and are received within said chamber.
