ABSTRACT:
A joint configuration for joining two articles of thermoplastic material by thermal bonding using an electrical heating element, wherein a female fitting having a portion with an enlarged diameter receives the end of an inserted pipe on two raised portions constituting lands on the inner diameter of the fitting, and the central annular recess between the two lands receives and positions the electrical heating element which fuses the thermoplastic material. The two lands, each compressed against the outside of the inserted pipe by an external clamp, confine and retain the fused thermoplastic material within the central annular recess to effect an increased internal pressure which promotes the formation of an extensive, continuous, and sound bond between the fitting and the inserted pipe.
