The reel has an elongated projection having first and second electrical contact areas onto which the phase wire and grounding wire are respectively arranged. The gas safety valve further includes an electromagnet having a core that is at least partially housed in an internal cavity of the reel. The safety gas valve also includes a support and a phase connector. The first electrical contact area is arranged such that it is inserted in the phase connector and the second electrical contact area is arranged such that it is inserted in the support, both electrical contact areas exerting an elastic force against the phase connector and the support, respectively, assuring the electrical connection between the phase wire and the phase connector, and between the grounding wire and the support, respectively. ## Claims ### Claim 1 A gas safety valve comprising: a support, an electromagnet comprising a core, the electromagnet being supported on the
