Coupler having protective bumpers and bands

Abstract

A coupler having at least one protective bumper is provided. The protective bumper is located on the exterior surface of the side of a movable sleeve of a coupler. The sleeve moves with respect to a main body of the coupler to lock or release a mating plug. A second sleeve of the coupler may also have protective bands. The protective bumpers and bands protect the coupler from damage as might otherwise occur from external forces acting upon it during use. Preferably, the diameters of the plurality of bumpers decreases the closer to the distal end of the sleeve the bumpers are located.
