Abstract

A connector which includes a female part having a barrel-shaped body, with a socket extending into the female part from one end of the barrel-shaped body. The socket includes first, second, and third step portions which respectively receive a flange, a shoulder, and a stem of a male part. A lip extends radially inwardly from the barrel-shaped body of the female part, with the lip having an inner diameter smaller than the outer diameter of the flange of the male part. The male part can be inserted into the female part by inserting the flange of the male part past the lip of the female part, such that the male and female parts are snapped together. In a presently preferred embodiment, a seal ring is disposed between the male and female parts, and the seal ring is compressed in an axial direction, thereby providing the connector with a fluid tight seal.

Dependent claims

A connector comprising:

(a) a female part having:
(i) a barrel-shaped body including a first end and a second end;
(ii) a socket extending into the barrel-shaped body from said first end, said socket including a first stepped portion having a first diameter, a second stepped portion having a second diameter, and a third stepped portion having a third diameter, said first stepped portion being disposed closer to said first end than said second stepped portion, said second stepped portion being disposed closer to said first end than said third stepped portion, the diameter of said first stepped portion being larger than the diameter of said second stepped portion, and the diameter of said second stepped portion being larger than the diameter of said third stepped portion;
and
(iii) a lip extending radially inwardly from said barrel-shaped body of said female part at said first end and
(b) a male part having:
(i) a stem having an outer diameter and
(ii) a flange having an outer diameter larger than the outer diameter of said stem,
whereby:
(c) in an assembled state, said stem is at least partially disposed in said third stepped portion and said flange is at least partially disposed in said first stepped portion.
