Abstract: An automatic disarming device for use with a portable personal protection apparatus in which the device disarms when taken from an authorized user thereby rendering the device ineffective or inoperative when turned against the authorized user. The automatic disarming device includes a housing supporting the personal protection apparatus, an operating mechanism on the housing for actuating the personal protection apparatus, and a removable arming member which renders the operating mechanism inoperative or ineffective when the arming member is separated from the housing.

Abstract: A holder for an aerosol canister. The holder has a housing and a cap. The cap receives the valve stem of the canister and when depressed will discharge the contents of the canister at a discharge nozzle in the cap. An annular locking ring has a projection which in one position prevents the cup from being pressed downwardly relative to the housing.
