だらしない emphasizes untidiness or lack of self-discipline in personal habits or appearance, while 締まりのない focuses more on lack of tightness, precision, or discipline in actions or things.
緩い is a simpler adjective meaning physically loose or slack, without the negative evaluative tone often carried by 締まりのない.
Phrase consisting of 締まり (noun form of 締まる, 'to be tightened') + の (possessive particle) + ない ('not'). Literally 'without tightness'.
