AbstractA connector which can couple a first profiled member having an internal compartment behind a slotted wall with a tubular second profiled member has an open-ended housing which is installed in the second profiled member and a one-piece profiled plate-like coupling member in the housing. The coupling member has two integral prongs with mirror symmetrical claws at their free ends, and followers adjacent the claws. The housing has integral cams which can stagger the claws by way of the followers in response to longitudinal displacement of the coupling member in the housing as a result of rotation of an eccentric which normally extends into a window of but is depressible into the second profiled member to permit insertion or removal of the connector. The claws can be introduced through the slot in the wall of the first profiled member to be thereupon staggered by the followers in cooperation with the cams in response to rotation of the eccentric in a direction to move the claws toward the housing. The coupling member has an integral spring which biases the eccentric into the window of the second profiled member.
