A disc brake for an automotive vehicle which includes: - a brake disc which extends in a plane transverse to a disc rotational axis with an axial orientation; - a fixed support relative to a chassis of the vehicle; - at least one braking pad which includes a vertical transverse lining-holder plate; -- which holds a friction lining a transverse friction face of which cooperates with an associated braking surface of the disc, the braking pad being axially slidably mounted in the fixed support between a front active position in which said friction face is bearing against the associated braking surface of the disc, and a rear inactive position in which said friction face is axially spaced apart from said associated braking surface of the disc, by a determined running clearance; -- which includes, at each of both its opposite transverse ends, a lateral lug with a transverse orientation which is slidably mounted in an associated slide of the fixed support; -- each lateral lug of which is fitted with a pad spring which is fastened to the associated lateral lug; - and at least one elastic return spring for elastically returning the braking pad to its inactive position including: - a fastening portion for fastening the elastic return spring to the fixed support; - a connecting branch, with an axial orientation parallel to the sliding direction of the braking pad, which is extended to an active tab which acts on the braking pad, characterised in that said active tab acts on a branch of the associated pad spring. - a brake disc which extends in a plane transverse to a disc rotational axis with an axial orientation; - a fixed support relative to a chassis of the vehicle; - at least one braking pad which includes a vertical transverse lining-holder plate; -- which holds a friction lining a transverse friction face of which cooperates with an associated braking surface of the disc, the braking pad being axially slidably mounted in the fixed support between a front active position in which said friction face is bearing against the associated braking surface of the disc, and a rear inactive position in which said friction face is axially spaced apart from said associated braking surface of the disc, by a determined running clearance; -- which includes, at each of both its opposite transverse ends, a lateral lug with a transverse orientation which is slidably mounted in an associated slide of the fixed support; -- each lateral lug of which is fitted with a pad spring which is fastened to the associated lateral lug; -- which holds a friction lining a transverse friction face of which cooperates with an associated braking surface of the disc, the braking pad being axially slidably mounted in the fixed support between a front active position in which said friction face is bearing against the associated braking surface of the disc, and a rear inactive position in which said friction face is axially spaced apart from said associated braking surface of the disc, by a determined running clearance; -- which includes, at each of both its opposite transverse ends, a lateral lug with a transverse orientation which is slidably mounted in an associated slide of the fixed support; -- each lateral lug of which is fitted with a pad spring which is fastened to the associated lateral lug; - and at least one elastic return spring for elastically returning the braking pad to its inactive position including: - a fastening portion for fastening the elastic return spring to the fixed support; - a connecting branch, with an axial orientation parallel to the sliding direction of the braking pad, which is extended to an active tab which acts on the braking pad,
