Abstract: A quick acting connector assembly is described for interlocking a portable member, such as a toilet seat, to a stationary member, such as a toilet, for example. The portable member carries a mounting bracket fixed to one margin thereof to present a planar flange or platform carrying headed pins projecting from one face thereof, with each pin located adjacent an enlarged opening receptive of a headed locking post extending from an underlying mounting plate fixed to the stationary member in assembly.
