Abstract: The invention relates to a fastener (10.1) comprising a housing with a plate (40.1) accommodated therein and an eccentric pin (30) rotationally mounted therein. The plate (40.1) has on the outer end thereof at least one hook (45.1) and a bevel (51.1) supported on a contact point (55.1) of the housing. In order to increase the stability of the fastener (10.1) and to allow a cost-effective production, the invention proposes that the housing be structured as a one-piece sleeve (20.1) open on both ends produced by bending a sheet cutout (60.1) multiple times. The two sheet ends of the sheet cutout adjoining one another in the sleeve (20.1) are connected to one another. The connection insures that an overturning of the eccentric disk (31) does not cause any bulging (58) of the sleeve (20.1). At least one first bend (78.1) is provided at least on the front end of the sleeve, producing a contact point (55.1) for the plate bevel (51.1).

Abstract: 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.

Abstract: A 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.
