ABSTRACT:
A frangible region is provided around at least one end of the outer connector part or cover of a hose and connector assembly, whereby a significant portion of such outer cover can be easily removed from the frangible connection to its end. This frees the end of the underlying hose to be removed from the inner connector part, a new hose part engaged over the exposed portion of the inner connector part, and a conventional clamp used to secure the new hose piece in place on the inner connector part. The outer jacket can be comprised of a plurality of bands, each band molded in place around a hose end, instead of a single piece outer jacket. The frangible region is created in the original molding process, and can, if desired, be formed on more than one of the ends of the outer molded connector part or the bands. The economics and durability of the original branched molded hose connection are still achieved, but the resulting connection can be repaired in the field, for example in site in the case of hoses used in automotive applications or hydraulic circuits using flexible hose. The frangible region is designed so as to direct and confine a breaking force applied to the outer connector part when it is desired to replace a hose piece.
