ABSTRACT:
The male portion of a connector assembly of the locking type has blades insertable into slots in the mating female portion, the male portion then being rotatable to lock the blades against direct axial extraction. A spring urged locking pin adjacent the trailing edge of at least one blade normally protrudes from the connector face, is pushed in by the female face, and then protrudes after locking rotation, entering the slot portion vacated by the trailing edge. A rotatable sleeve on the male connector body has a cam surface which, upon rotation of the sleeve in the unlocking direction, first retracts the locking pin, then engages the body of the connector to rotate the blades out of their locked position.
