<p>The invention relates to an element for fixing a construction piece on a supporting piece. According to the invention, the said element comprises a clamping piece (1), for a construction piece on which there is also fastened a hollow anchoring leg (2) with which it may be anchored in a through hole of the supporting piece, the cylindrical wall of the anchoring leg (2) being provided with two opposite openings (4), which get to the clamping piece (1). From the interior edge of the opening (4) there protrude two pairs of elastic arms (5 and 6) which open widely in the direction of the clamping piece (1), both pairs of elastic arms (5 and 6) being provided with steps towards the clamping piece (1), by starting from some exterior corresponding edges (11 and 12), which are situated at the longest radial distance in relation to a central axis (M). Some frontal and in stepped surfaces (7, 8 and 9, 10) are made in different horizontal planes, they may support on the interior side of the supporting piece, some other contact surfaces (13 and 14) being made, in the same time, at radial distances different from the central axis (M) and they may support on the peripheral surface of some holes with various diameters.</p> |
