ABSTRACT:
A plate-like front element (20) is provided adjacent but not constrained to the needle tube (11) and foldable on itself about a first folding axis (A) parallel and close to the tube A. A rear element (30) is also provided for constraining the needle support member (12) to the front element (20) such that this can be rotated about a second folding axis (B) transverse to the axis of the tube (11). The device can assume a first operating configuration in which the element (20) is folded on itself about the first axis (A) with the front portion of the tube (11) enclosed between the two fins (21, 22) of the element (20). The device can assume a second operating configuration in which, by rotating the front element (20) about the second axis (B), the tube (11) projects forwards of the front element (20).
