A metric continuum X is called retractible provided that each of its subcontinua is a retract of X. It is known that such continua are 1- dimensional, as well as that hereditarily locally connected continua are retractible. It follows that the class of all retractible continua has neither a model in the class of all continua nor a universal element.
