Abrégé

A retainer which can be easily connected to a flexible pipe provided in a narrow space. A retainer (24) surrounds a through-space (200) through which a flexible pipe penetrates. When the flexible pipe has penetrated through the through-space (200), the retainer (24) prevents the flexible pipe from retracting and coming out of the through-space (200). The retainer (24) is provided with retaining sections (84) and an affixation section (86). The retaining sections (84) individually engage with the outer peripheral surface of the flexible pipe. The retaining sections (84) are affixed to the affixation section (86).

A joint for a flexible pipe, configured in such a manner that a pressing ring cannot be inserted into the joint by mistake without the flexible pipe being inserted in the joint. A joint (10) for a flexible pipe is provided with a joint body (20), a seal member (22), and a pressing ring (24).  The seal member (22) has an engaging section (61).  The engaging section (61) is pressed by a flexible pipe (300), which is inserted from a pipe insertion hole (63), to move the seal member (22) to an insertion completion position.  A hindering section (64) is provided behind the seal member (22).  When pressed by the pressing ring (24), the hindering section (64) becomes located ahead of the pressing ring (24) so as to face the pressing ring (24) to prevent the pressing ring (24) from entering recesses (84, 94) in a snap ring (26).

A joint for a flexible pipe, the joint being configured in such a manner that a flexible pipe having a tip portion with a deformed cross-sectional shape is prevented to a certain degree from being connected to the joint. A joint (10) for a flexible pipe is provided with a joint body (20), a seal member (22), and a pressing ring (24).  The pressing ring (24) has an inlet section (79a) into which a coating layer of the flexible pipe enters and also has a body communication section (79b).  The inlet section (79a) allows the tip portion of the flexible pipe to penetrate therethrough and also allows the coating layer of the flexible pipe to enter thereinto.  The body communication section (79b) is, when the pressing ring (24) is inserted in the joint body (20), positioned further toward the joint body (20) side than the inlet section (79a).  A circular opening (87) through which the flexible pipe passes and which has a diameter smaller than the outer diameter of the coating layer and greater than the outer diameter of crests of the flexible pipe is provided in that portion of the body communication section (79b) which is a boundary contiguous to the inlet section (79a).

Abrégé

Provided is a joint for a flexible tube, which does not have a tendency to allow leakage of fluid therefrom. The joint body (20) of the joint (10) for a flexible tube comprises an insertion hole (40), a first storage section (42), a seal member diameter-reducing guide section (48), and a second storage section (44).  A seal member (22) comprises a body section (60a) and a single annular section (60c).  The body section (60a) is pushed deeply into the second storage section (44) by the end of the flexible tube (300) stored in the joint body (20).  The single annular section (60c) is drawn into the second storage section (44) when the body section (60a) is pushed deeply into the second storage section (44).  When the single annular section (60c) is drawn into the second storage section (44), the single annular section is engaged with the root section (312) of the flexible tube (300) by the seal member diameter-reducing guide section (48).  After the single annular section is drawn into the second storage section (44), the single annular section seals the gap between the inner periphery of the second storage section (44) and the outer periphery of the flexible tube (300).
