ABSTRACT:
A catch member adapted to be secured to the end of a grille member for securing same to a window parallel to the inner surface thereof. The window sash presents inwardly facing surfaces which have longitudinally extending shallow grooves forming seats of the catch members. The catch members comprise a stem and a head portion integrally formed therewith. The head portion has a base from whose lower surface the stem depends, and an arcuate arm flexibly secured to the base along one edge thereof. The arcuate arm overlies the base and its major portion is spaced apart from the upper surface of the base whereby it can yield when the window grille is being fitted to or removed from the window. The arcuate arm is curved in one direction and flat in the opposite direction.
