Abstract: An electrical connector having a receptacle means including a receptacle shell and a plug means including a plug shell, coupling means including a coupling housing engaged with a coupling nut for rotation of the coupling nut, the coupling nut having threaded engagement with the plug shell and the coupling housing having a breech lock means engagable with cooperable breech lock lands on the receptacle shell, the plug means and receptacle means being adapted to be fully electrically mated and locked by rotation of the coupling housing through about 90.degree.. An arcuate detent member of about 180.degree. keyed to the plug shell for relative axial movement and received within an annular groove in the coupling housing for resilient forcible selective engagement of opposite radially outwardly enlarged ends of the arcuate detent member with two sets of radially outwardly formed recesses in the coupling housing.
