Abstract

A coupling apparatus (10) which comprises a body member (12) having a cylindrical bore (14) with a first cap (36) engaged with the body member (12) at a first end thereof and a second cap (74) engaged with the body member (12) at a second end thereof. A first annular seal (66) is disposed within the bore (14) of the body (12).
Optionally, a second annular seal (64) is disposed within the bore (14) of the body (I2) and engages with the first annular seal (66). A
plurality of locking members (44) are slidingly engaged with the body member (12) and register with the first cap (36). When the coupling apparatus (10) is coupled to a cylindrical member (32), the first cap (36) engages the docking members (44) forcing the locking members (44) into locking engagement with the cylindrical member (32). When the first cap (36) is disengaged from the lacking members (44), spring members (56) urge the locking members (44) out of locking engagement with the cylindrical member (32).
