The river sense is from c.1300, on notion of "barrier, enclosure." Wrestling sense is from 1608. The lock of a firearm (1547) probably so called for its resemblance to a door-latching device.

safety 
c.1300, from O.Fr. sauvete, earlier salvetet (11c.), from M.L. salvitatem (nom. salvitas) "safety," from L. salvus (see safe). Meaning "trigger-lock on a gun" is attested from 1881.
