Bed frame members are provided for quick, snap-together, interlocking assembly for preventing relative rectilinear motion between members without loose or screwthread parts. One frame member has a first slot with an enlarged retaining portion and a mating frame member has a projection disposed thereon for entrance into the slot. The projection carries a Belleville washer having its conical convex face disposed for engagement with the slot for compression as the projection moves into and for retaining engagement with the periphery of the enlarged retaining portion of the slot when the projection has been fully inserted in the slot. A second slot in one of the frame members has a portion thereof disposed at a substantial angle to the first slot and receives a second projection disposed on the other frame member. When the second projection is positioned within the angularly disposed portion of the second slot, the Belleville washer may be detentedly engaged with the retaining portion of the first slot by relative rotary motion of the two frame members which are then locked from rectilinear motion relative to one another, and may be disengaged only by relative rotary movement to detentably disengage the retaining member from the retaining portion and from the first slot, after which rectilinear motions will disengage the second projection from the second slot.
