A connector which can separably couple a hollow first profiled member with a channeled second profiled member has an open-ended housing for a reciprocable clawed coupling member and an eccentric which is rotatable to move the coupling member between extended and retracted positions. The coupling member has a front projection which can be pushed by a disc of the eccentric to move the coupling member to extended position in which the claw or claws of the coupling member can enter a channel of the second profiled member. The coupling member further includes a rear projection which can be pushed by the disc to move the coupling member to the retracted position in which the claw or claws bear against an internal surface of the second profiled member and urge an outer side of the second profiled member against the adjacent end of the first profiled member. The rear projection is part of a looped rear end portion of the substantially plate like coupling member. The rear end portion can form a U-shaped loop or a complete loop.
