Abstract:
1. Apparatus for connecting a fitting to a conduit section comprising: a rigid insert having a generally cylindrical body with a proximal end and a distal end and defining a central lumen, said central lumen extending between said proximal and distal ends, said proximal end being adapted to be received in the conduit section while said distal end projects from the conduit; and a rigid, one piece retainer, said retainer being generally ring shaped and having an opening sufficiently large to receive the insert, said retainer having a sidewall defining a first end facing the distal end of the insert, a second end facing the proximal end of the insert, and an inner surface defining an opening extending from the first end to the second end, said sidewall having a varying thickness such that a diameter of the opening is generally constant from said second end to a position intermediate said first and second ends and then gradually increases from the position intermediate the first and second ends toward the first end.
