A ground fault receptacle housing for an electrical device having a backing portion with a base and a wall extending from the base. The wall has a hoop portion that forms an exterior channel extending therethrough. A cover portion is adapted to couple to the backing portion and has a front face with apertures therein for access to the electrical device. A wall extends from the front face and has a substantially inflexible post extending from the wall. The post has a body portion and a tapered protrusion thereon, the protrusion having a largest perimeter that is greater than at least a perimeter in portion of the exterior channel. When the protrusion passes through the channel, at least a portion of the hoop portion stretches, while the wall extending from the base of the backing portion remains substantially stationary. The protrusion is adapted to engage the end surface of hoop portion after passing through the channel, while the body portion of the post is positioned within the channel without substantially stretching the hoop portion when the protrusion engages the end surface. |

DETAILED DESCRIPTION Accordingly, an object of this invention is to provide an improved electrical receptacle housing.
Another object of this invention is to provide an electrical receptacle housing, which can be easily and rapidly assembled.
Still another object of this invention is to provide an electrical receptacle housing having a two-part housing, which is difficult to disassemble.
Yet Another object of the present invention is to provide an electrical receptacle housing having a two-piece housing, which are coupled together using a snap-fit connection, rather than the more conventional fastening means.
The foregoing objects are basically attained by providing a electrical wiring device housing, comprising a first section having a first wall, a first side wall extending from the first wall, and a connecting unit extending from the first side wall.
The connecting unit has a connecting wall that has a normally substantially planar configuration and is spaced from the first side wall and an end wall that is adjacent the connecting wall.
The housing also comprises a second section that has a second wall, a second side wall extending from the second wall, and a post extending from the second wall.
The post has a barb at the distal end thereof, the barb is adapted to pass between the connecting wall and the first sidewall and engage the end wall of the connecting unit.
The first side wall remains substantially stationary while at least a portion of the connecting wall flexes away from the first side wall when the barb passes therebetween, and the connecting wall returns to the normally substantially planar configuration when the barb engages the end wall.
By forming a electrical wiring device housing in this manner, the housing is quick and easy to assembly and is extremely difficult to disassemble.
Other objects, advantages and salient features of the invention will become apparent from the following detailed description, which, taken in conjunction with the annexed drawings, discloses preferred embodiments of the invention
