Lockable Hose Coupling

A standard quick disconnect hose coupling is modified to lock only in a correctly connected position.

A hose connected to a sleeved female portion of a Jiffy-Tite quick disconnect water coupling (such as Model No. JS-308*) manufactured by the DME Corporation, is normally snap fitted into a male portion permanently attached to a mold. It is possible to connect the two portions together into a partially engaged position ("A" in Fig. 1), Which will cause water leakage and possibly could result in a dangerous disconnection under pressure.

The cornector is modified by cutting a semicircular notch in its sleeve and adding a locking pin. A properly connected coupling is defined as one where the pin and notch are not aligned ("B" in Fig. 2). A partially, improperly, engaged coupling cannot have its sleeve rotated because the pin is then present in the notch ("C" in Fig. 1).

Once the two coupling sections are properly engaged and the sleeve is rotated, the coupling cannot be detached without first aligning the pin and notch. Large numbers of couplings can be rapidly inspected by noting the relative positions of their pins and notches. *Also for Model Nos. JS-204, JS-205, JS-206, JS-214, JS-215, JS-216, JS-224, JS-225, JS-226, JS-318, JS-328
