Abstract: A connecting system can couple two waveguides to one another, wherein each of the waveguides comprises a flange or a protruding rim. When the waveguides are connected together, the flanges can face one another in an adjoining arrangement. The connecting system can comprise two members, each having a groove, recess, or slot that receives a circumferential area of the adjoining flanges. The two members can be disposed on opposite lateral sides of the waveguides with each groove embracing a peripheral area of the adjoining flanges.

That is, the two members can clamp around opposing sides of the flanges. In response to the flanges moving deeper into the grooves, the sidewalls of the grooves can compress the flanges together to attach the waveguides to one another.

An aligning pin is mounted on said first assembly in a location so as to engage the lever arm camming surface when the locking structure is physically moved along the transceiver housing channel from a first position to a second position.

Abstract: Quick release interconnection of waveguide circuits terminated at least partially by a standard flange is achieved by rotation of a clamping ring which surrounds the first circuit termination and cooperates by means of outer grips with a groove in a base mounted on the second circuit. Tight engagement is obtained by means of protruding pins carried by a sleeve fastened to the first circuit guided by semicircular cams and locked in a recess in inclined spring guides carried by the inner face of the rotatable ring. Disengagement is obtained by rotating the ring counterwise. Fool proof interconnection is obtained by a unique means protruding from the standard flange and registering with a unique recess in said base.
