With respect to the handset, a removable anchor is positioned intermediate the receiver and transmitter ends along the hand-grip portion, the inside walls of the hand-grip being provided with a ledge or other means for transmitting longitudinal pulling forces along the restraint cable as a shear force along the peripheral sidewalls of the hand-grip portion.
The housing anchor is specifically adapted for elbow type public telephones, and utilizes an elbow with the extremity of the armored telephone cord and restraint cable assembly and the cable stop fitted into the elbow generally parallel with the sidewall of the housing.
