ABSTRACT:
An electrical plug comprising a base having connection pins secured therein, end portions of such connection pins projecting from the front of the base and opposite end portions thereof extending through the base and being respectively connected to respective connection terminals to which respective conductors of a connection cable are also connected. The material and shape of the base are such that it bends in response to a pulling force of a magnitude less than the tensile strength of the cable, exerted in a direction approximately transverse to the connection pins between the cable and the projecting end portions of the connection pins. Further, the connection pins are so secured in the base that the force required to extract any connection pin is greater than the tensile strength of the cable. Consequently, pulling of the cable can never result in a loose connection pin being left behind in a wall socket in which the plug has been inserted.
