A relatively inexpensive electric soldering iron and handle structure can be constructed so as to be relatively simple to assemble by utilizing cooperating holding elements within a tubular handle to form a holder. This holder serves to support or hold a socket adapted to support a heating element and a cord retainer in place within the handle. The holder is in turn held in place within the handle through the use of cooperating detent elements on both the holder and on the handle. The parts of the soldering handle structure are dimensioned so that the parts previously identified can be inserted as a unit into the handle through one end of the handle as the cord is withdrawn outwardly from the other end of the handle.

A soldering iron can be constructed using a heating element structure or first part connected to a handle structure or second part through the use of connectors on these parts which are adapted to be secured together through the use of a rotary or twisting type motion. The handle structure includes a spring biased sleeve which projects from it toward the heating element structure. The heating element structure includes a metal flange which is resiliently engaged by the sleeve when the parts are connected together. This flange in effect forms a part of a tubular, metal housing used to connect a body disposed in proximity to the heating element so as to conduct heat away from the heating element and the connector on the heating element structure. The housing serves to protect the heating element structure against physical damage and is grounded through the flange and the sleeve to an appropriate grounding wire leading from the handle structure.
