Abstract

The invention relates to a tool-holder frame (13) for a loader such as in particular a loader (11) intended for agricultural use. Said tool-holder frame is to be secured to at least one tool (15) including at least one recess (16) capable of engaging with a locking element (21, 22) for locking said tool (15) to said frame (13), said frame (13) including: a means for sliding said locking element (21; 22) between a locked position, in which said element (21; 22) can be received in said recess (16) when said tool (15) is secured to said frame (13), and at least one unlocked position, in which said locking element (21; 22) can extend outside said recess (16) when said tool (15) is secured to said frame (13); and a means for retaining said locking element (21; 22) in said unlocked position and including a bearing means. According to the invention, said retaining means is movably mounted in said sliding direction such that said bearing means can engage with said tool (15) when said tool is secured to said tool-holder frame (13), and mounted on the stationary frame of said tool-holder frame (13) when said tool (15) is separated from said tool-holder frame (13) and in a longitudinal direction perpendicular to the sliding direction of said locking element (21; 22) so as to enable the release of said locking element (21; 22) when said tool (15) pushes said retaining means in said longitudinal direction.
