Abstract
Abstract A device for ensuring retention of electrical plugs in outlets includes a base plate and a selectively releasable retaining member saddle. The base plate is semi-permanently secured between the face plate of the outlet and the wall. The base plate preferably is rectangular and includes a pair of arms which extend from opposite edges of the base plate and which are perpendicular to the plane of the base plate. The arms each include a complexly configured channel which receives a pair of spaced apart pins extending from the retaining member. The retaining member is generally U-shaped, having parallel sides which slidably engage the base plate arms and a slot centrally disposed on the base of the U-shape which receives a cord. The pins on the retaining member cooperate with the channels in the base plate arms to retain it there, to limit it to pivoting motion to receive a plug and its associated cord and to releasably secure the cordal plug, thereby securing the plug in the outlet.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
165 words
A device for ensuring retention of an electrical plug in an outlet comprising, in combination, a base plate for disposition on an electrical outlet, a pair of parallel arms extending from said base plate, each of said arms defining a slot extending through said arm, each of said slots having an elongate portion extending generally away from said base plate and an end portion extending generally perpendicularly to said base plate and intersecting said elongate portion of said slot at its end most distant said base plate, each of said arms also defining a plurality of blind slots extending through said arms and oriented at an acute angle to said base plate and intersecting said elongate portion of one of said slots, and a generally U-shaped retaining member, said retaining member having pin means disposed in said slots of said arms for slidably securing said retaining member to said arms of said base plate and a centrally dispose slot means for receiving an electrical cord.
Claim 2
Independent Claim
165 words
A device for ensuring retention of an electrical plug in an outlet comprising, in combination, a base plate for disposition on an electrical outlet, a pair of parallel arms extending from said base plate, each of said arms defining a slot extending through said arm, each of said slots having an elongate portion extending generally away from said base plate and an end portion extending generally perpendicularly to said base plate and intersecting said elongate portion of said slot at its end most distant said base plate, each of said arms also defining a plurality of blind slots extending through said arms and oriented at an acute angle to said base plate and intersecting said elongate portion of one of said slots, and a generally U-shaped retaining member, said retaining member having pin means disposed in said slots of said arms for slidably securing said retaining member to said arms of said base plate and a centrally dispose slot means for receiving an electrical cord.
