A connector detachably connects two structural elements (6, 7), of which one element (7) has an engageable edge (8) and the other element (6) has an elongate cavity (9) at an end adapted for the connection. The connector comprises a first sleeve (2) which has the same cross-sectional shape as the cavity and is formed with a longitudinal bore and a transverse bore; a second sleeve (3) insertable in the transverse bore of the first sleeve and formed with a bore alignable with the longitudinal bore of the first sleeve, and with a threaded bore extending transversely of said alignable bore; an elongate clamping body (1) which is insertable through the longitudinal bore of the first sleeve and the bore aligned therewith in the second sleeve, the outer end of the clamping body having a hook adapted to engage the above edge, and the portion received by the second sleeve having an oblique surface; and a locking screw (4) rotatable in the threaded bore of the second sleeve for displacement transversely of the clamping body, the point of said locking screw being applied against the oblique surface under the action of a spring bias between the first sleeve and the clamping body. When the clamping body (1) is received in both the first and the second sleeve (2, 3), the second sleeve is displaceable transversely of the first sleeve to a position in which the second sleeve (3) is completely contained in the first sleeve (2). |
