  • Patent number: 4682389
    Abstract: A multi-piece garment connector is provided for interconnecting related garments or the like so as to prevent accidental separation of one from the other, as during laundering. The connector comprises male and female elements connectible temporarily to related garments such as a pair of hose, each element being provided with a simple attachment device, and the two elements are interconnected by fitting a tongue-like part on one element into a cavity in the other element. Cooperative parts of the elements provide a detent function operative normally to prevent withdrawal of the tongue from the cavity but yieldable to manual force to separate the cooperative detent portions as to enable such withdrawal.
