1. A housing for electromagnetic valves, adapted to internally receive a core and allow the core to slide therein for switching said electromagnetic valve;
at least a portion of said housing being adapted to be surrounded by a coil comprised in the electromagnetic valve;
said housing extending along an axis, and comprising a distal end and an open proximal end;
said housing comprising a locking system adapted to lock said coil;
wherein said locking system is integrated into said housing and is located at a distal end of said housing;
said locking system being adapted to assume:
a first configuration, in which the locking system allows said coil to be positioned around and removed from said at least a portion of said housing;
a second configuration, different from said first configuration, in which the locking system locks said coil around said at least a portion of said housing;
said locking system in said first configuration has an outside diameter of a known value;
said locking system in said second configuration has an outside diameter which is greater than said known value;
wherein in the first configuration, said locking system maintains said known outside diameter as said coil is positioned around said housing and as said coil is removed from said housing;
wherein said locking system is configured so that, once the locking system has assumed said second configuration, the locking system cannot assume said first configuration again.
