Abstract: An improved two element locking construction for releasably securing the side edges of a shower curtain to the outer surface of a shower enclosure to prevent leakage of water outwardly of the enclosure and reduce the inward motion of the curtain. The construction includes a first element which is secured to a surface of the enclosure using a suitable pressure sensitive adhesive, the first element forming a recess. A second element is secured to a surface of the shower curtain adjacent a vertical edge, and has a shaped longitudinally extending projection selectively engageable with said first element in an interstice leading to said recess. Disengagement of the elements is accomplished by manually flexing a resilient wall of the first element to temporarily enlarge the insterstice engaging the projection on the second element.
