An electrical connector device which provides for a sealed, weather-proof electrical connection in an electrical circuit. The electrical connector device includes a first housing element having a pair of first electrical fittings projecting therefrom and a second housing element having a pair of second electrical fittings projecting therefrom so that when the first and second housing elements are positioned next to each other the first and second electrical fittings cooperate with each other to complete an electrical connection. The first housing element also includes a pair of circumferential first flanges, each first flange surrounding a different one of the first electrical fittings, and the second housing element also includes two sets of concentric second and third circumferential flanges, each set surrounding a different one of the second electrical fittings. When the first and second housing elements are positioned next to each other with the first electrical fittings electrically connected to the second electrical fittings, the first circumferential flanges are each received in the annular space between the second and third circumferential flanges of a different one of the sets of second and third circumferential flanges to create a seal around each of the interconnected first and second electrical fittings.

A vehicle pneumatic brake system is disclosed wherein a transfer valve of advantageous design responsive to supply pressure is employed to provide service pressure to an anti-lock, pressure modulating valve for so long as supply pressure is greater than a preset minimum and to provide pressure from a protected reservoir (tank) to the anti-lock, pressure modulating valve when supply pressure is below such minimum value.

A tractor-trailer electrical receptacle is disclosed wherein a housing contains a cavity having a plurality of male contact members mounted therein; the cavity is adapted for receiving a mating electrical plug. A mounting member connected to the housing is adapted for mounting the housing at an angle inclined to the horizontal to promote drainage of any moisture in the cavity away from the contact members. A support member extends forwardly from the housing to provide such support for an electrical plug mated with the receptacle as minimizes the effects of vehicle vibration upon such plug. A cover is connected to said housing and urged by a spring to close the cavity when a plug is not inserted in the receptacle.

A clamp is provided for securing a plurality of elongated articles in a spaced relationship; the clamp includes a base provided with standards which have recesses or wells therein and which mutually define a recess therebetween to accept such articles of a plurality of sizes. In addition the clamp includes a pair of straps, one of which is connected to the base at one end thereof and includes a tongue and fastening sections; the other strap is connected to the other end of the base and includes complementary channel and fastening sections for mating with the tongue and fastening section of the former strap.
