Abstract: An exchangeable member is secured to a carrier in a shuttleless loom by an elastically yielding mounting element having a head, a shank, and a neck between the head and the shank. The exchangeable member has a bore aligned with a bore in the carrier. The mounting element is pulled through the bores so that the neck snaps into place in the bores under tension while the head and shank bear against outer surfaces to hold the member and carrier together. The mounting element has a nail type shape with a long shaft that is threaded through the aligned bores and pulled for tensioning the neck. The exchangeable member is, for example, a member that is subject to wear and tear that must be exchanged frequently such as the guide body of a gripper head which forms the carrier for the guide body.
