The invention relates to a retractable leash for animals, having a housing containing
a spring-biased reel in which the remaining length of leash can be taken up and
which is stoppable by an actuating mechanism for adjustment of the maximum extension
length of the leash as required, and by providing for the slack section of the
leash to be taken up automatically by the reel when this maximum extension length
is not being used, thus ensuring that the leash is always taut without restricting
the animal's freedom of movement unnecessarily.
