There is disclosed a device (1, 34) for positioning a first element (24) with respect to at least a second element (25) by means of a resilient locking member made in a single piece and having two ends (2, 3) connected by a bar (4) capable of being resiliently deformed in its axial direction (5). The longitudinal resilience of the bar (4) is due to the fact that it includes a plurality of apertures (11) over its length, said apertures (11) being located alternately on either side of a median plane (14) of the bar (4). This locking member can easily be manufactured in the form of a moulded plastic part.
A locking member for holding a first element relative to a second element, comprising a head arranged for co-operating with said second element, one end opposite said head and an intermediate portion able to be deformed resiliently in a longitudinal direction of said member and made in a single piece with said head and said end, wherein said intermediate portion is formed by a bar, which, transversely, has smaller external dimensions than said head and said opposite end.
A device for holding a first element with respect to a second element, comprising a recess arranged in said second element and a locking member comprising a head arranged for co-operating with said second element, said locking member further comprising one end opposite said head and an intermediate portion able to be deformed resiliently in a longitudinal direction of said member and made in a single piece with said head and said end, said intermediate portion being formed by a bar, which, transversely, has smaller external dimensions than said head and said opposite end, said locking member being mounted in a hole of said first element such that a distal portion of its head can emerge from a surface of said first element to co-operate with said recess of said second element.

The present invention concerns a locking member for holding a first element relative to a second element, comprising a head arranged for co-operating with the second element, one end opposite the head, and an intermediate portion that can deform elastically in a longitudinal direction of said member and integral with the head and the opposite end.
More precisely, according to a first aspect, the present invention concerns a pin, the opposite end of which forms a tail, arranged to be disposed in a recess provided in the first element.
Similar devices are known from the prior art in various areas of application, like for example in the horological field.
The invention will be better understood using the following description of different embodiment examples with reference to the annexed drawings, in which:
FIG. 1 is a perspective view of the locking member according to a first aspect of the present invention;
FIG. 2 is a perspective view of a simple mechanical construction example comprising the locking member according to the present invention;
FIGS. 1 to 3 illustrate respectively the structure and working of a locking member 1 and the corresponding device made according to a first aspect of the present invention.
In the perspective view of FIG. 1, it will be noted that the locking member, also called “pin” hereinafter, has a generally cylindrical shape comprising three main portions, namely two ends forming respectively a tail 2 and a head 3 delimiting an intermediate portion forming a bar 4.
In the preferred embodiment shown in these Figures, the casing of pin 1 according to the invention has rotational symmetry about axis 5.
