Gentlemen:
Over on this side of the world (USA) our NEC (2008) mandated all 15-20 amp, 120 volt residential receptacles be "Tamper Proof". That caused quite a stir during the NEC Code Change seminars, mainly due to 'cost'. WE have all receptacle devices, 15 & 20 amp, 120 volt 'on the shelves' in all configirations, including GFCI devices.
Aside from that, we used to have a variety of faceplates that were 'child resistant' (aka Tamper Proof), but to my understanding most, if not all have lost the UL Listings/Labeling required for legal sale.
Tech info on the TR devices is available at the various mfg websites; Pass & Seymour, Leviton, etc.
Take care & stay safe
