A connector releasably connects two building elements (6, 7), one (7) of which has an engageable edge (8) and the other (6) has, at the connection end, a cavity (9). In the cavity, a first sleeve (2) of the same cross-sectional shape as the cavity is insertable therein. The sleeve has a longitudinal hole (10) for receiving an elongate clamping member (1) which includes, at its outer end, a hook (18) for engagement with the engageable edge. The part of the clamping member received in the longitudinal hole has a bevelled surface (16) to cooperate with a clamping screw (4) which, when turned, is movable transversely of the clamping member to a position with its tip against the bevelled surface under spring bias between the first sleeve and the clamping member. The bevelled surface (16) is arranged in a transverse recess (15) in the clamping member (1). Into this recess, a second sleeve (3) having a threaded hole (14) for receiving the clamping screw (4) can be depressed, against the spring bias, to a position in which the second sleeve (3) is located completely inside the circumference of the first sleeve (2). |
