Abstract: A press-stud with lateral locking, having a male component and a female component which must be associable with each other, the female component has a seat which is suitable to accommodate, by insertion, the head of a mushroom-shaped element which protrudes from the male component; the seat can be accessed by the head through an opening which has a first larger part which allows insertion of the head and a second smaller part whose dimensions are intermediate between the dimensions of the head and the dimensions of the stem, the seat accommodating elastic contrast elements which allow the head to move over them during insertion and extraction, with a movement of the head toward the first part of the opening that is larger than the second smaller part, and viceversa.

Abstract: A press-stud comprising a female part (11; 317) to which one end (14; 318) of a male part (15; 330) is anchored in the closed configuration by forcing with elastic deformation of a ring (12; 100; 200; 311; 411) that is accommodated in a circumferential groove (13; 316) formed inside the female part (11; 317), the ring being closed, being made of elastomeric material, and being accommodated in the groove (13; 316).
