An electrical connector for connecting an electrical conduit to a wall of a junction box having an opening therein and having edges surrounding the opening. The connector includes a connector body defining a conduit-supporting passageway having a conduit central axis, a proximal end, a distal end, and a sidewall extending between the proximal and distal ends, the distal end formed with a locating collar substantially encircling the connector body, the locating collar functioning to engage the edges of the opening in the junction box. The connector further includes a pressure lock mechanism for selectively and removably securing the connector body to the opening in the junction box.

1. An electrical connector for connecting rigid or flexible electrical conduit to a wall of a junction box having an opening therein, edges surrounding the opening and a surrounding interior surface of the wall surrounding the opening and a surrounding exterior surface of the wall surrounding the opening, comprising: a one piece connector body defining a conduit supporting passageway having a conduit central axis, a proximal end, a distal end, and a sidewall extending between the proximal end and the distal end, the distal end formed with a substantially cylindrical locating collar having a leading lug and an opposed trailing lug and a recess having a bottom substantially encircling the connector body, the recess being sufficiently deep that when the connector body is tilted and the leading lug of the locating collar is urged toward the edge surrounding the opening and the bottom of the recess contacts the edge surrounding the opening, the opposed trailing lug of the locating collar can pass through the opening and the locating collar can then be centered to engage the edges surrounding the opening in the junction box and the surrounding interior surface of the junction box and maintain the conduit central axis substantially perpendicular to the wall of the junction box;a pressure lock mechanism for removably securing the connector body to the opening in the junction box, the pressure lock mechanism comprising a sleeve extending outward from the sidewall of the connector body having a central axis that is substantially parallel to the conduit central axis, a threaded bolt securing fastener engaged in the sleeve having a distal end, the securing fastener having a central axis substantially parallel to the conduit central axis and substantially perpendicular to the wall of the junction box, wherein the securing fastener can be selectively tightened to cause the distal end of the securing fastener to abut completely and solely against the surrounding exterior surface of the wall of the junction box and to draw the locating collar tightly against the surrounding interior surface of the junction box with sufficient force to prevent the dislodgement of the connector body from the opening, and selectively loosened to cause the distal end of the securing fastener to separate from the wall of the junction box whereby the connector is selectively secured to or removed from the junction box. 2. The electrical connector as claimed in claim 1, wherein the connector body defining a distal-facing bearing surface, and the locating collar functioning to engage the edges of the opening and the surrounding interior surface of the junction box comprises: a foot portion comprising the leading lug defining a leading perimeter edge, the trailing lug defining a trailing perimeter edge, and lateral walls connecting the leading perimeter edge and the trailing perimeter edge, the leading lug and the trailing lug each defining a proximal-facing seating surface, and the lateral walls having a proximal edge and a distal edge, a locating ledge formed on the leading lug proximal-facing seating surface and defining a leading locating surface and proximal-facing locating surface, the proximal-facing locating surface sloping from a central high point to the proximal edge of the respective lateral walls; and a locating collar formed adjacent the trailing lug so as to be positioned between the distal-facing bearing surface on the connector body and the trailing lug. 3. The electrical connector as claimed in claim 2, wherein the sleeve extends outward from the sidewall over the leading lug such that a distal end of the securing fastener when secured to the junction box opposes the leading lug proximal-facing seating surface. 4. The electrical connector as claimed in claim 1, wherein the connector body comprises a distal flange extending at least partially about the connector body and the engaging portion is formed distally of the distal flange. 5. The electrical connector as claimed in claim 4, wherein the distal flange on the connector body extends outward past the perimeter edge of the trailing lug.
