1. In conjunction with a plate element having a plurality of fluid passageways therethrough, and cap elements for each of said passageways, a means for resiliently retaining said cap elements in vertical relation to said plate, comprising a hold-down rod member concentrically of each cap having a lower end dependent through said passageway below the plate, a clamping bar member engageable with the lower ends of a series of said rod members, bolt means freely supported by said bar member extensible vertically upward therefrom into endwise engagement with the lower surface of said plate, and expansion spring means between said bolt and bar adapted to extend the bolt upwardly, said bolt means when in engagement with the plate cooperating with said spring means to exert a resilient downward pressure against said bar resiliently resisting upward movement of the cap, rod and bar members.
