A torch includes a head member with a bulb unit, a tail member with a cell unit, and a bellowed intermediate flexible hose member threadedly connected to the head and tail members. The head member includes an on-off switch for energizing the bulb unit upon actuation. The hose member includes a hose body, two connectors respectively attached to two ends of the hose body, and front and rear conductive contact sets respectively provided in the connectors in such a manner that the front conductive set is in electrical contact with the bulb unit while the rear conductive set is in electrical contact with terminals of the cell unit. Each of the front and rear conductive sets includes an insulated tubular holding seat fixed within the corresponding connector and provided with a reduced-diameter outer end portion, an annular conductive ring sleeved around the outer end portion, a conductive mushroom-like contact element press-fitted within the end portion of the seat. A central wire extends through the hose body and the corresponding seat and has an outer end extended into the blind hole of a corresponding element so as to establish an electrical connection. A peripheral wire extends through the hose body and the seat to be in electrical contact with the ring. The ring and the element serves as two electrical contacts.
