Abstract

An elastically resilient fastening clip is described which serves in particular for the fastening of trained fruit trees, vines, or the like to horizontally extending training wires. The clip comprises a slit loop the slit of which is widenable outwardly for introduction of a twig or the like part of the afore-mentioned plant and, after passing the plant part therethrough, closes again under the clamping effect of the loop of the fastening clip exercised at both sides of the slit. The clip further comprises hook parts bent at angles away from the slit in the loop; and, when the clip is fastened to the training wire, a contact zone of the loop opposite the slit is destined to lie essentially along one side of the training wire, and the slit and the adjacent hook parts are destined to lie on the other side thereof. A plant part introduced into the loop is pressed resiliently against the training wire, while, at the same time, the clamping tension caused by the insertion of the plant part prevents a lateral displacement of the clip along the training wire. The loop is provided with a hooklike projection or nose in the contact zone by means of which nose the contact zone can be hooked on to the training wire. The loop further has two crimped intermediate leg zones between the ends of the contact zone and the slit, and has generally the shape of a flat isosceles triangle with rounded angles, the slit being situated in the vertex of the triangle, while the base of the triangle forms the aforesaid contact zone, and the wire-engaging nose is in the middle of the same.

An elastically resilient fastening clip, in particular for the fastening of a trained plant including fruit trees, vines, or the like to a horizontally extending training wire, said clip comprising a slit loop (10) having a slit (11) which is widenable outwardly for introduction of a sapling, a twig, a shoot or the like part (8) of said plant and, after passing the plant part (8) therethrough, closes again under the clamping effect of said loop (10) of said fastening clip exercised at both sides of said slit (11);

and said clip further comprising hook parts (23,24) bent at angles away from said slit (11) in said loop (10);
said loop (10) having an elongated compressed or flattened shape in the plane in which the loop extends, and further comprising:
(a) a contact zone (14) extending opposite said slit (11) and approximately parallel to said training wire (5),
(b) two crimped intermediate leg zones (12,13) between the ends of said contact zone (14) and said slit (11), and
(c) a hook-shaped projection (17,18,19) having a nose part (19) bent out of the plane of the loop in the middle of said contact zone (14), said nose part (19) lying opposite said slit (11), being adapted for being hooked on to said training wire (5) by contacting the latter from that side (A) of the wire on which the bent-away leg parts (12,13) are located;
whereby, when said clip is fastened to said training wire (5), said contact zone (14) of said loop (10) comes to lie along one side (B) of said training wire, and said slit (11), said adjacent leg parts (12,13) and nose part (19) are on the other side (A) thereof, and, when said plant part (8) is introduced into said loop (10), it is pressed resiliently against said training wire (5), while, at the same time, the clamping tension caused by the insertion of said plant part (8) pulls said contact zone (14) into frictional contact with said training wire (5) and thereby prevents a lateral displacement of said clip along said training wire (5).
