1. A quick connect fitting for an electrical junction box comprising:
- a hollow electrical connector through which an electrical conductor may be inserted having a leading end thereof for insertion in a hole in an electrical junction box;
a circular spring metal adaptor surrounding said leading end of said electrical connector which also has a leading end, a trailing end, and an intermediate body, said circular spring metal adaptor being less than a complete circle when on the electrical connector and when separated from said electrical connector has a relaxed diameter, less than the diameter of the portion of the connector which it surrounds;
at least two spring locking members carried by said metal adaptor that spring inward to a retracted position to permit said adaptor and locking member to be inserted in a hole in an electrical junction box and spring outward to lock said electrical connector from being withdrawn through the hole; and
an arrangement on said connector for limiting the distance said connector can be inserted into the hole in the junction box.

Abstract
A spring steel adaptor (20) that improves the ease of use and reduces the time involved in securing electrical connectors to electrical junction boxes (34). Several embodiments are disclosed which require the use of a zinc die-cast connector (26) having a smooth central section (32) to accommodate the spring steel adaptor (20). A separate embodiment employs a spring steel adaptor (20) that is designed to be used in conjunction with any of the standard size threaded electrical connectors that are presently in use in the electrical industry.

12. A split circular spring metal adaptor for utilization with a standard hollow electrical connector for permitting a quick connect fitting of said connector in an electrical junction box with said connector having an arrangement for limiting the distance said connector can be inserted into the hole in the junction box comprising:
-
a split circular spring metal adaptor having a diameter smaller than a hole in an electrical junction box into which it is to be inserted; and a series of inward tensioner/threading tangs lanced from said adaptor that are staggered to coincide with threads on a standard electrical connector to permit the threading thereon of said adaptor.

14. A method for quickly connecting fittings to electrical junction boxes comprising:
-
providing an electrical junction box with a hole; providing an electrical connector having a leading end for insertion in said hole; providing a circular spring metal adaptor surrounding said leading end of said electrical connector with said spring metal adaptor having a divided circumference of less than a complete circle when placed on said electrical connector and when separated from said electrical connector having a relaxed diameter of less than the diameter of the portion of electrical connector which said adaptor surrounds; providing at least two spring locking members on said spring metal adaptor that have a relaxed outer dimension greater than the diameter of said hole; and inserting said spring metal adaptor and electrical connector into said hole until said spring locking members have gone entirely through said hole and spring back to a locking position to prevent said adaptor and electrical connector from being withdrawn. - View Dependent Claims (15)
