The device includes an open topped housing, the bottom of which is interconnectable to a vehicle steering column through an adapter plate. A biasing plate is slideably supported in a horizontal position in the housing on a number of spaced vertical posts secured to a base plate in the housing. The biasing plate bears a number of spaced ridges extending up from the periphery thereof and defining peripheral recesses therebetween. A horizontal ring locking plate is fixed to the top of the posts above the biasing plate and bears spaced teeth defining a number of notches therebetween with the teeth partially overlying the biasing plate ridges. Coiled springs on the posts push up the locking plate. A lever secured to the biasing plate is needed to selectively move that plate down from the locking plate. A keylock in the housing extends out therefrom and releasably locks the biasing plate up against the locking plate. The device also includes an inverted cup-shaped steering wheel hub connector cap which has on its underside a central plate bearing peripheral projections matching the notches in the locking plate. The connector cap can be pressed down through the locking plate to depress the biasing plate sufficiently to permit rotation of the steering wheel and cap plate to positively lock the projections in the biasing plate recesses below the locking plate teeth.
