The electrical plug guard comprises a disc member having a pair of elongated slots to frictionally receive the prongs of an electrical plug. The slots have centers offset with respect to each other along the length of the slots. The slots are effective to skew the prongs of the plug with respect to each other when the prongs are inserted in slots through the disc member. The disc member has a thickness sufficient to prevent finger contact with the prongs which are electrically active when partially inserted into an electrical plug outlet.

DETAILED DESCRIPTION The disc member, generally designated 10, includes a pair of elongated slots 12 and 14 which frictionally receive the prongs 16 and 18 of an electrical plug 15.
Slots 12 and 14 have centers 11 and 13, respectively, which are offset with respect to each other along the lengths of the slots.
The slots are effective to skew the prongs 16 and 18 as shown with respect to each other when the prongs are inserted therein.
As shown in FIG.
3, the prongs are partially inserted through the disc member 10.
In the front elevational view of FIG.
4, the prongs 16 and 18 are shown to be twisted along their own respective longitudinal axes 17 and 19.
When the electrical plug 15 is inserted into the outlet 20, the frictional force is increased.
Thus it makes it more difficult for a small child to put the plug into an electrical outlet in the first instance.
Furthermore, once the plug has been completely inserted into the electrical outlet as shown in FIG.
6, it becomes more difficult for the plug to be removed.
If the child is strong enough to pull the plug partially out or to partially insert the same in the electrical outlet, the size and shape of the disc 10 is sufficient to prevent finger contact with the blades 16 and 18 which become electrically active when only partially inserted into the outlet 20.
The embodiment shown in FIGS.
7 and 8 are particularly adapted to the polarized plug.
That is, slot is longer than slot to receive electrical prongs 30 and 28, respectively, which have different lengths along their widest cross-sectional measurement as shown.
The centers 25 and 27 are still offset with respect to each other along the length of the slots 24 and 26, respectively.
The embodiment as shown in FIGS.
9 and 10 incorporates an opening 36 along with the elongated slots 32 and 34.
This disc member 31 is particularly adapted to a three-prong plug having a ground prong 37 along with the electrical prongs 38 and 40.
Again, the centers 33 and 35 of the respective slots 32 and 34 are offset with respect to each other
