Gilmour 5/8" Ergonomic Garden Male Hose End Mender 58CPM
Product Review (submitted on September 4, 2012):
I bought one of this type from another brand. It worked fine but was hard to tighten enough to not leak.
This brand was even more difficult to tighten. The rubber band around the end slipped when I tried to tighten it. I had to cut it off and use a pliers to tighten it. This is just poor design. It does look like it will last since it is metal and well built under the rubber.
