ABSTRACT:
The subject matter of the invention refers to the technical area of vehicles in general, of cycles and similar vehicles and their fittings and accessories.
A rod (4) or equivalent means is mounted in the lower bracket (1) perpendicularly to the cylindrical recess axis (1b) and secant with the peripheral part of said recess, to assume the dual function of holding the bolt (2) with respect to the bracket (1) and end stopping the rotation of the tensioning arm (D) integral with the bolt (2) with respect to the bracket (1) because of the suitable arrangement of a bearing surface (2d) of the bolt which is in the plane and opposite the rod (4); an elastic means (5) for retensioning the tensioning arm being mounted inside the bracket and suitably connected to the bolt on the one hand and to said bracket on the other hand.
