a) The invention concerns a spring for maintaining a first part and pressing it on a second part. b) The spring for compressing a first part (5), provided with at least a stop (14), against a second part, is characterised in that it consists of a wire with a constant cross section urged to exert pressure in one or several points of its main part (4), provided with two curved ends (2 and 3) co-operating with two housings (11 and 12) of a support, so as to produce, after it has been fixed on said support, a twist for maintaining the pressure of the points of its main part (4) with the stop(s) (14) or for pivoting inside the two housings (11 and 12) along an axis which is substantially parallel thereto, thereby releasing the pressure exerted on the two parts (5 and 6) resulting in the separation of said two parts. c) The invention is useful for maintaining a part and its pressure and more particularly a printing head in a printing device.
